Hello, looking at the Barton Street Series 528 Hemi. And was curious what you guys are running for street strip Hemi combos. I would need to be able to get my 70 Challenger in the high 10s to make it worth while. Thanks

My current build nearing fruition. 528, early '70 factory heads unported but casting flash/protrusions removed, some used rocker assembly pieces but mostly new indy stuff, diamond pistons making about 10:1 with cometic head gaskets, reconditioned factory conrods (couldn't stomach using Chinese rods and couldn't afford American ones), a used stroker crank ground -.010 rods and mains, early 66-67? intake with Vanke modification, edelbrock 1407 carbs with '66 afb lids, some used, rough hooker super comp headers. I haven't bought a cam yet, but I'm looking at lift numbers .550-.600, lsa 110-112, and duration @.050 between 245-255.

It's going into a lightened '70 RR and my realistic goal is 12's this year. Later I plan on upgrading to aluminum heads with a single plane and single carb to hopefully make it into the 11's.

I bet barton's cam will have much more duration along with better flowing heads than i'll have. Depending on the rest of your combo, high 10's may be a reasonable goal.

I have been collecting parts for years for my Hemi project to replace the 500" wedge in my '70 Cuda. I found a new World iron block and MP al heads on Racingjunk. I had the heads ported by MCH a few years ago on their last "holiday deal". Then found a used Barton intake, a set of DLI rockers, a pair of DC valve covers, a good set of used spark plug tubes, used fuel pump, dist, etc.

This winter it is finally time to order the reciprocating assembly, cam, and other pieces of the puzzle. I have talked to several of the Hemi builders about the stroker kit and cam combo and was surprised at the different approaches to the same end.

Ultimately, I ordered a 10.5:1 540 kit and stepped up flat tappet cam from Ray Barton. I think the 528 has a 4.15 stroke and the 540 has the 4.25 stroke. They were basically the same price, so I went with the longer stroke.

I can't wait to get this puppy finished and in the car.
WOO-HOO!

It shouldn't take a 528 HEMI to go high 10s.

Of course you don't need 528, but the bigger the displacement is, the milder the rest of the engine can be. The OP wants a street & strip engine.

The OP needs to provide more info on the car. You can run high 10s in a street and strip E body with an OEM-head 440 with the right combination.

Wow that's pretty impressive! Is that your combo? I'd like to hear more about it, that sounds really stout for an OEM wedge head!

I suspect that PorkyPig could be referring to my Challenger, although from a LONG time ago (around 2000).

Yeah, it dipped into the 10.9s at 122+ with a stock-stroke 440 using ported '452' iron heads and 254 at .050 flat-tappet cam. Total street car, since I drove it about 500 miles the weekend it first broke into the 10s, too.

Aftermarket heads and a bigger cam shaved off about a half second in ET, but I could have probably squeezed another 1-2 tenths out of it w/ those old heads, too.

But "streetable" is defined by what the owner is willing to put up with. I have 4.10s and a pretty loose converter (4K+ stall). The OP may have a completely different expectation of what's still "streetable". It would take more cubes & torque to run that fast if 3.54s and a low-stall converter are in the plan.

The bigger the C.I. and the more power and torque you make the easier the rear tires will spin Trust me on that My old 1970 Cuda 4 speed NHRA legal went high elevens(11.79 at 117. MPH) back in 1975 on nine inch bias ply slicks with 4.10 gears, that rascal had 2180 lbs on the front tires and 1280 lbs on the rear tires without the driver It was a real tire spinning rascal

So if I've got all this straight, and bear with me here I'm a little slow, the OP shouldn't build more cubes than he needs because excess power will overwhelm his tires, and instead he should build a smaller engine with a looser converter and drag gears for his street/strip car.

By golly I've been going about this thing all wrong on my build too! Good thing you guys are here to set me right. Guess i had better dumpster all my hemi junk, buy a 318, and shove as much nitro through it as possible because it'll be just as fast. Who needs stinky ole displacement anyway!

On a serious note, if the OP is willing to buy a street oriented crate style hemi, it may be safe to assume the car in question is mostly for street driving with the occasional drag strip blast. If that's truly the case, I really think more displacement would better suit his goals.

I hope the OP chimes in soon so we don't have to guess.

605 all Aluminum Hemi pump gas street/strip build here...

Mine...Is back out of the car for an unintentional cam update...Shooting for +800hp on pump gas...I did get some driving on it before a lobe on the cam left probably due to the fact I did not remove the inner springs during break in.......Wow is all I can say as it is an absolute beast.

If mid 10's is all you want, we have been running 10.52 out of our 474 pump gas Hemi street engine...Does nice 2ft wheelies as well on those runs in a '69 A body that is for sale.

Ahhh... 10's with a factory 440 and OEM heads??? I am calling BS on that comment.
The OP asked what others were running so he could get some idea's for his build.

I already posted what I had that fit the description of a 440 with ported OEM heads that could run high 10s, so there is nothing bogus about that.

BTW, he didn't say "factory" 440, he said a 440 with OEM heads.

My 605 made enough power to bend the frame rails, gussets, and braces everytime I tried to make a pass in the truck. After pulling about 100hp out of it, it labored to a 10.49@128. It really needs a back half.Dave

I hope the OP realizes that half the battle with getting any street car to ET decently is chassis tuning, tire selection and driver experience. Adding a big engine to an otherwise unsorted out combination is just asking for tire smoke and sub-par ETs. Any snarky comments to the contrary are delusional.

Yep, I'm just looking for some combos, or what is needed cam, head and stroke wise to get a 3800lb Challenger into the tens. The current motor in my Challenger is a mild 470 that is a mid 11sec et. So I don't want to spend Hemi money to go the same et.
I have seen several videos of 528 Hemis only running 11s. So I don't want to make those mistakes. This will be a car that is mostly drivin on the street. But will see a drag strip 2 to 3 times a year. Thanks guys

It can be done, we have run 10.87 on a +.030 440 with OEM heads and a steel crank at 446 cubes....It takes work to do, and a good combination of parts. The car cannot be super heavy either and probably isn't the most daily driver friendly, but we have done it....With a stroker, the ET drops into the 9's on pump gas RB with after market heads.

I agree with you as if you build a big torque monster you can go fast without pushing the eng to hard. Thats sorta what I did as I built my 493 so it would make enough power to get me in the 10's without pushing 7500 rpm or building a super trick build. It was easy on my budget and easily met my goal. I have no problem hooking on 9" slicks but I dont make the power a 528 Hemi will but I guess I make close to 600 flywheel hp. Ron

I been going about it all wrong also, I got this 572 Hemi build going and I screwed up. For the same amount of money for the rotating assembly I could have bought a 604 stroker kit. Now I'm loosing sleep wondering how much power I lost making a uninformed decision. I 'm not worried about tire spin, if your just spinning your tires just driving around , your front brakes must be hung up.

Mega block,68 stock irom heads,good valve train,reak good bottom end.9.5's at 144+ on pump gas @3900 lbs.Boost is where it's at
