Hey people! I would appreciate any advice on a certain subject. I am getting ahold of a firebird and the guy I'm buying it from tells me that the engine and transmission are freshly rebuilt for performance. That's all well and good, but the guy says the engine is a chevy 350 2-bolt block. I don't have a problem driving this, but I want more power out of the engine. He says it probably has about 300-325 horsepower. I want around 400-425 hp. should i get a cheap 4-bolt block and work with that , or will a 2-bolt hold up? I don't intend to do any turbocharging, supercharching, or NOS. Also, the guy tells me that this was a RECON ( they build chevy engines, sell them in Summit mags) engine. I'm just not entirely sure which way is the better way to go, because I've heard that 2-bolt main chevy 350s can't handle but so much Horsepower. Help!
