stock bbc fuel injection system, a performance oriented computer plug and play. So you can add bigger cam headers and compression. Gm performance has everything to build this high torque performance engine. I hope this helps answer your question.

LOOK THESE "COMIC" BOOKS LIKE CAR CRAFT AND ALIKE HAVE A VESTED INTEREST IN HAVING DYNO RESULTS THEY DO IN THEIR FUDGED ARTICLES!!

If anything of value come from them is a knowledge of how to read between the lines.Even at that,there is sooooooo much B.S. in the articles,you best off taking to heart the advise given on here.
True thats why I want to build a performance package that would yeald 500 hp with 9.4:1 compression then take 12% of the horsepower by taking a way two points from the compression down to 7.5:1 would yeald 440 horsepower. Plenty for a street motor. 87 octane fuel, no stress on parts. The motor would last forever. With mobil 1 sinthectic 5 w 30.

If compression level gets too low,you may not get a good fuel burn

Most EFI systems i've seen, help dial up torque in the low and mid rpm, better milage--- start up cold and drive off. nothing can replace a Holley carb for high mid rpm to high rpm.

Arless, you'd be a whole lot more credible if you were asking intelligent questions instead of relating magazine builds to us. You may not have been there and done that, but we have.

I am familiar w/that CC article about the $2,650 big block Chevy. And I have built a 454/468 BBC that used c/n 236 peanut heads that I ported (~220cc avg. intake volume). So I know from first hand experience that the numbers represented in that particular CC article are not fudged any more than whatever correction factor that may have been used.

Bottom line: Peak numbers of 446 hp at 4,900 rpm and 542 ft/lb torque at 3,600 rpm from a 9.4:1 454 BBC is not even close to being unrealistic using the XE268 cam and other parts they used.

I love an article that gets a lot of power and torque from really cheap parts. That big motor would last a lifetime with less than 5000 rpm for max power. 3000 lb car or truck with an overdrive th 400 and 330 gears. Just the way I like a street everyday driving engine.
