Please tell me how to achieve 600rwhp with a n/a lt1. the only way i know of is exotic heads like dominions or sb2.2, even mindgames 15* head combo netted under 600rwhp.

Yep he did and is one of very few, and do you know how much his engine cost, and who it was made by? Ok then....

Who's Jim?

I'd like to hear more about his setup..... is it n/a?

Chuck (Progressive Race Engine Development) has an sb2.2 swapped LT1 in his shop that'd be well over that 600 rwhp mark.... even behind an auto. Saw the dyno numbers on that one when I was down there.... stout.

It depends on how much you will spend, and how far you want to go.

The "easiest" way to run 10's N/A with an lt1 would be to build a nice stroker with some good heads. Either bigger ported 23 degree heads like 200cc + Afr, or 18* or 15* degree heads would be even easier to make the power, but they would cost more for the heads, and conversion, etc. Then you could run a mild cam and , make the power pretty easy.

The easiest would be to use the 18 or 15* heads, but then the whole setup would cost more$$$$, but you could run 450 - 500+ rwhp pretty easily with a mild cam.




As far as the power , it DOES NOT take 600rwhp to run 10's even in a full weight fbody . Unless you have a 4000+lb car with a huge system and weight 3xx. Of course traction and driver skill play a part, but I think we are talking about the needed HP. Even , an Impala could probably run tens with less than 600rwhp.

Even a full weight fbody should probably take somewhere between 460rwhp - about the low 500rwhp range to run 10's. Of course driver skill and traction play a part, but again i think we are talking just about the needed power, and not whether the person hooks or can drive. 460rwhp - ~500rwhp would give you the hp to run 10's though, even in a full weight 4th gen fbody. Especially an auto with a good converter.

I'm pretty sure Jim's numbers were made on the engine dyno...as I don't believe the motor's seen the inside of an engine bay as of yet.

well, it can be done, but i didnt say it was gonna be an affordable motor...


lots of inches, huge throttle body, 50lb injectors anyone? amazing heads, and a cam with more curves than pamela anderson (before the "reduction"). vague, i know, but the point is that although i dont have the $$$ to get an NA motor with 600 horses, i'm pretty sure that someone else does... *crosses fingers for lucky lotto numbers*


oh yeah, i've been lookin for that gm magazine for 2 days and cant find the friggin thing...i think it got thrown out by my B*tch ex.

Yep. And unfortunately, we'll never know what it would have made on an engine dyno with a fully functional ignition, because it's being boxed up to ship right now. Mark doesn't have the time to dedicate to it any more, so it's going to be installed as-is.

However, "as-is" is definitely over 640 horsepower. Mark said 647 was the highest they saw, but on the pull he sent me numbers for (see link below), it made 641 @ 6,600 rpm and 637 @ 7,400 with a big dip in between (down to 586 @ 7,000) caused by the Opti, apparently.

There's more than likely some serious power yet to be discovered now that I have an eDist and LS1 coil packs, but I won't know until I get it on a chassis dyno. It's definitely not going to be 600 RWHP, though. 570-580 maybe, but definitely not 600.

Of course I do have a bit of a weight advantage. The car should come in around 2,700 lbs. when finished.
