Hello guys I just finished reading Hot Rod Magazine's "HUFF & PUFF" article in "Horsepower Handbook: Big Block Chevy and "How To Build Big Inch Small Block Chevys".
A few weeks ago at Summit Racing Motorsports Park a fellow I had spoken to on another Forum a few years ago was running Mid 11's which was off pace for his GTX. (He runs a Pump Gas 6-71 Supercharged 446 CID Mopar BB with a Air to Water Intercooler, his times are normally in the low 10's with this simple setup & a Heavy car.)
Both the SBC and the BBC are potent engines as witnesssed by Rob Mixx's 700+ HP E-85 383 SBC and Hot Rod's 825 HP 454 BBC.
A SBC has 1 advantage over the BBC it is lower in weight.
Here are the 2 options Desired output 580-725 HP/520-650 LB FT TQ:
I) A +.040 overbore forged pistons 8.25-8.75:1 CR, 454 block, forged 3.766 inch crank, forged 6.385 rods, a HYD Roller Cam 114 degrees LSA, Edelbrock's New Aluminum heads, an 8-71 Blower underdriven to deliver 6-8.5 PSI, twin E-85 830 DPs.
II) A +.040 overbore forged pistons 8.25-8.75:1 CR, Dart Iron Eagle or World Motown block, forged 5.85-6.0 rods, a HYD Roller Cam 114 degrees LSA, AFR 220 CC ported heads,an 8-71 Blower underdriven to deliver 6-8.5 PSI, twin E-85 830 DPs.
I know option 2 will most likely have the higher price tag but will be able to grow a couple of times.
Which option would you choose for a short wheel based light car like a Chevy Vega Coupe, Datsun 510 Sedan, or Ford Anglia/Thames?
