As you'll see I know next to nothing about engines so bear with me. Got a GM crate 350 with Edelbrock performer intake and Brawler carb, headers and H-pipe. This is just a street car that I'd like it to raise the hairs on my arm when floored. Not a strip car. Runs ok now but not very exciting. Anyway have a neighbor that has a 327 that he says we can build for around $3k and have a very fun motor. My 350 is in good shape no known problems. My question to start with is what are the pro and cons of 327 vs 350. Useing the $3k figure will I be better off(happier) with dumping the money in the 350 or building the 327? By the way the 327 is running at the strip every Saturday and very dependable in a 69 Camaro. 6 sec 1/8th mile. Said we'd get al heads and different pistons intake and cam. That's about the extent of my knowledge on it. Hope this is enough info to start this discussion. Thanks for everyone's help on other topics you've helped on and looking forward to you all's thoughts on this.
