Hi Scot, with an adequate wallet you should find several engines of interest in the PAW calalog. To partially respond to your dyno-software question, I have not bought any yet but I have studied in considerable detail Ryans SBC dyno page:

The comment above about low rpm torque being better for the street is in agreement with my views.

Thank you for the references, Don. Yes, I have read through the entire site at Ryan's. Excellent reading!?! I particularly like that Ryan has discovered God drives a Chevy...probably a '70 425hp 396 Camaro SS

Also, I ordered the PAW catalog today. It should be here in about 3 weeks (years)!!! I have been reading the websites of Jesel, Brodix (got that catalog today), Chapman, and CompCam, as these are the known parts in the American Speed 377.

Looks like a guy could spend $40 to $300 on this kind of desktop dyno software. Don't think I want to go there without seeing it, or at least speaking with someone that has used it before.

While I do agree that low-end torque is important, the GTR only weighs 2,200 lbs wet. So the low end of low-end torque may not be as important for this rig. My Impala, on the other hand, has more torque than HP. It weighs in at about 4,200 lbs.!

The close-ratio transaxle is designed for about 8k RPM max. The 377 should turn 7,500 without over-stressing the assembly. I don't know what the piston ft. per second rate is for that RPM, but the parts makers will have to support that requirement.

Don - Tech1,
Here are some additional high-HP combinations with forced induction (starting on page 8):

Thanks again,
