My personal favorite has always been the 4.3L V6 that was used in the Syclone. That was an awsome truck. It could out run anything in 1991.What would you rate a CHEVYS ten best performance motors ?
327 is good, 350 is good, 454 is good, 427 L88 is awesome, 502 is good, 572 is good.
The 350 as always been a good engine, but the 427 L88 in its' day was Great, still is for the most part.
327, 69 camaro 302, that bad *** 400 305 for dependability, 350 carb. for cheap horsepower. LT1 for both dependability and horsepower, LS1 for dependability, H.P, and gas mileage, then LS2, LS6, ZL1.
the new LS7 7.0 427 in the Corvette Z06. WORLD class....... its the same engine in the Corvette C6R. just built a lil different. yes, the class dominating C6R..... LONG LIVE THE VETTE!!!!
I agree with the girl, the 302 was bad a** and it reved high it was pretty good at higher rpms, around 7300 and it wasnt the best at 4000 rpm but the 327 was a bad engine too, and if your looking for a big block the new 572 and i like the older 427 aluminum block in the zl-1 camaro
