Hey, two things. First, a 350 Chevy is a bitch engine. Chevy put it in everything from Corvettes and Camaros to Blazers and Tahoes. Your 454 could rip a 350's ass in three different places
. I own a 1970 LS6 SS454 Chevelle and El Camino (Just bought my Elky
) I also have owned three 350 camaros, and a couple of 350 Chevelles. Believe me, the 454 is sooooo much better. Second thing, my Chevelle, stock, made about 450hp, and now with a blower, dual dominator carbs, headers, and forged aluminum pistons, it makes around 1100hp, and Ive only spent about 5 grand. (bought the car for 2 grand) This engine is so strong, I even run a 350 hp shot of nos, and Ive never burned a ring, piston or gasket. As soon as I get a digital camera, Ill show you my cars. I'm a severe racing enthusiast. I only own one car with less than 8 cylinders. A modded 1987 Buick GNX with twin turbos and nos. Peace!!
). As far as putting in a 350 to replace your 454, you're asking if you should do it....ummm, NO. All things being equal, the 454 will always out-power a 350. There's no substitute for cubic inches. If you put a blower on both motors, the 454 will be stronger, if you put nitrous on both motors, the 454 will be stronger...and on and on. But if you're really into a 350 swap, heck, send your 454 to me...I'll gladly take it
