if money wasn't an issue, what would be the combo from block to carb to build the biggest and most powerful small block ever ? all motor, no add-ons. so let me here these combo's guys......

I don't know much about them. But the pro stock truck small blocks were pretty Bad AZZ! I think Patterson was building them I'm sure someone will chime in.
DC

Drag Race? Road Race? NASCAR? Salt Flats?

Don't forget boat drags/ racing

The most potential is going to be from a w8/48 degree deal, but frankly, i have personally not yet seen anything in that configuration NA that runs near what you would "think it should"
Dont know if nobody has hit on the right combo or what, or maybe there are cars out there i dont know of.

If i was going to make " for sure" big power, i would probably use the indy raised port 245 cnc deal on a 48 degree block,430-450 cubes, with lots of compression, big roller, pro systems dominator, light rings, good evac system, etc.

I would think the above combination, well sorted out, would propel any 3000 pound ish car into the 8's easily

Seems like the WoO Sprint Cars make amazing horsepower. Not sure what combo they use, though.

Digital radio killers couldn't even stop this one.

Well there are a number of small Hemi's in Comp Eliminator that run pretty dang hard.

In other words start with a factory Mopar small block, throw it in the dumpster, build an entirely new custom design from scratch, and you'll have a killer engine combo.

well....depends on your definition of a small-block....

you're looking aftermarket block for strength.....

a P5 head probably has more raw HP potential than any W7/8/9,
but there, you're talking very little in common with a factory SBM, save maybe bore centers.

bar none, the latest 5.7/6.1 hemi package has the most potential power of any stock "small block mopar" layout. they share bore spacing, bore, stroke, & main bearing size with older LA motors, and could be lumped into the "small block" category just as easily as a P5 engine or even a 48 degree W7/8/9 motor...

realistically the OEM 6.1 heads, max ported, have as much raw flow potential as a W7/8/9, plus the added benefit of no valve shrouding due to the valves opening up away from the bore...

P5 Hemi in my book wins it hands down....

No question.

another one for the R4 block P5 head.

mine is pretty bad according to all the eggspurts on this site. wrong parts, wrong, this, wrong that, just plain bad.

P5 set up with GT4788 twin turbos on methanol should be good for 2000 HP.


That would be killer

The R4 P5 stuff is way cool,but you cant go real big on the cubes because the block..and those engines are way hard to find..

Here is a good run down on a very high HP small block,with wedge head...

R3 block
60mm cam almost a inch lift
420 to 440 cubic inch
very light weight crank aka,LA enterprise,winberg,etc
GRP rods,
custom Diamond pistons
A double throw down set of W8 10 to 13 degree CFE heads.
CFE sheetmatal manifold
dual 4500 dominators
external single stage peterson oil pump with star vacuum pump.

I think you could make 1050 to 1075hp..yes with a wedge head!!

I also think you could get 1000hp with cast manifold,single four at 420 to 440 inch also

We got 384cfm out of a full port production 6.1 casting head with a stock 2.08 valve. Nothing exotic at all. Its the low/mid range numbers that really make the heads stand out.

The 6.1 HEMI stuff is awesome no doubt. But, they are limited cubes and valve lift.

The R4/P5 stuff is awesome, Limited cubes

W8 not running good NA and talking up the Indy's Come on put the joint down. 8.4's in a backhalf doorslammer NA aint fast.

I feel a few years ago my 468 CID W8 with a cast intake and single 4-barrel made big power NA. No dyno sheets to prove it but with a nitrous cam and converter it ran 150MPH at 3,400 lbs NA.

The awesome engine would be a 6.1 based hemi aftermarket head and block that could go over 500 inches with sheetmetal intake and 4 split dominators. Or a P7 casting drag race ported with an XR block in place of the Hemi.

Everyone is scared to order a custom billet crank and make big cubic inches. I have ran many larger than 400 inch combos. I'm sorry but the bigger you go the more power they make as long as it can breath.

The match racers Sonny builds for have no better available parts than what is being promised for the small block Mopar. I just don't know why Mopar guys even talk about it. Obviously none have the will to pay for it. I have had a 900 HP small block for sale for over a year. Complete for $20,000. I get the PM's from people who thought they could build cheaper all the time after they find they couldn't. It's hard to see people manufactur parts for the small block mopar when truth is the sales won't pay for the paper it took to draw the plans up.
