Doug, what rear gear do you run? 31” tall tire?

Hope to let you know soon.

4.56 with either 33x15 GY or Hoosier 10.5x33. Trapping 154 best at 7400 rpm. I assume you will be running a 4speed?

Thats what im talking about !!! WHat kind of HP did that make???

10.5Wx31 M/T. Currently has a 4.30.. It's also had a 4.10. Not much difference. 7200-7300 depending on weather.

DO rules dictate the 3300lb weight?? it would be nice to see what it would run at 2900-3000

Tough to get a NSS car much lighter. Tubular K members and racks are not legal. They must have "full" interior, meaning no gutted cars. An aluminum block would be the biggest weight loss for Doug at this point.

Not sure on the trans. It will not be the Jerico.

That MegaBlock has to go !!! LOL Id be all over an aluminum block and there got to be some more hitchhikers on there....IF there no weight limit id be cutting everywhere lol , I know his car is pretty trick but id be looking all the time for that extra lb

we have 2 nss hemi cars. one with mega block weighs 3150 and goes 8.80s. the other has alum block and weighs 2950. not yet sorted out.
both are 64 plymouths all steel less hoods.

64 with Aluminum but that is huge money. Might have to acid dip a few panels to take some weight off. NSS with a 605 Hemi, some were I live are making a lot of HP over 1300 but you start to live on the edge. Would rather back the motor off and go 899 without hurting things. Only other way I see it to change to a 67 8 9 A Body. there is your weight loss and 67=8=9 all have Big Blocks and 68s Hemis. One problem that was found is the front end on a 68 Cuda with a 605 making a lot of HP the MPH at the top end makes the front end of the car feel very lite,

figure 6 to 8 percent slip for the auto, so the stick might want that much more gear.

Not a mopar but fast. Grand Am 3200 pounds 278 cube small block Chevy, did have a 266 but went back. 8.30-40s last time I heard. Comp Car. Shifts at 10,500 11,000 I think. I’ll call him tomorrow to see how fast now.

It could get lighter for sure. As stated an aluminum block would be the biggest move. Still has steel bumpers and deck lid. Also the American 200s are heavy. But I like the way it looks. This year it should around 3310- 3320 race weight with me (195). I think Jakes quoted weights are without driver.

Just for info swapping out from a 528ci Mega block to a 572ci KB saved only 70lb, heads (572-13) exhaust and induction were all the same, no other changes. We eventually knocked off 4 10ths and added 5 mph to the terminal, best for best.

I know you said "NA" and there are plenty that do that. However, they are probably pretty radical and expensive motors not to mention the gearing/converter you have to use.

Just curious, why "NA"? Class rules, etc?

I ask because a single turbo and a decent motor will get you there easily and it will be super driveable.

I am at 3,480 lbs with a "Magnum" series stock block motor 389 CI, home ported Eddy heads, .520 hydraulic roller, 9.5:1 compression, T4 78mm turbo, 3.55 gear, 3,500 converter, shift at 6,000 cross a 6,000, through full exhaust with power steering, power brakes, etc. So far on only 13 lbs of boost I have run 9.9's. I am going to up the boost this fall to 17 lbs (which is about the limits of this "cheapo" turbo) and should be in the mid 9's at almost 3,500 lbs. Drop the weight to your 3,100 and it is still a little short at around 9.teens.

The goal of my truck was 10.9's and it was built with that in mind. But I plan to upgrade to either a better T4 turbo or go with a T6 88mm and should be able to run solid 8's at almost 400 lbs more, which is your goal.

Just my .02

Why? It's a simple bracket car. Don't know many that are running a turbo, and going rounds at a bracket race.

If the point of the question is to determine 'can it be done' for your own current new combo of parts. My answer would be 'absolutely'. There are alot of ways to skin a cat. Would most run a manual trans in a bracket car? etc etc...Answering the question at face value, because at 3100lbs you'll need a good 850HP, I'd say SS valve orig B1 'clean-up' ported (see IMM porting threads) on a 572" shortblock...(because I like Big blocks) And I'd use either a t400 or PG on a midplate/adapter. That being said Dartin' is using the 345 cnc Indy's on a 540 with only 12.5:1 and a .730 net lift 'gentle profile' 306/273 cam. At 3100lbs around here he'd be in the 8's in good air.

Ok, I didn't see where you mentioned it was for a "simple bracket car", at least in the initial post. But you can still use a turbo for bracket racing. Lots of turbo cars are deadly consistent and have a great top end charge which is good for a bracket car. Good luck in whatever option you take!

Tell 'em if he wants a brand new alum. low deck Wedge KB block, I still have a brand new one sitting in the crate that I am most likely not going to use now. I'm about to post it for sale, but others who know I have it keep in touch from time to time to see if I'll sell it. I hit them up yesterday and getting some interest, but no takers yet. It'll definitely help with weight loss if the rules will allow for the class.
