Let me start off by stating that I come from the import world, I know a fair bit about fixing engines and have put a few together but am new to building them.
My uncle recruited me for a project, building a 350 for a car that he found. He said he wants about 450hp out of it, and wants it to be reliable and streetable. All I have to start with is a one piece rear, 4 bolt main 350 block factory set up for roller lifters. I am going to make this my official question thread and hopefully you guys can help me through this and we can make a sweet engine. (did I mention that money is no issue "as long as cost doesn't get insane" :D)
So first off I was thinking Scat 383 rotating assembly, specifically part number 1-41823BIE. Forged crank, forged 6" connecting rods, forged +5cc flat top pistons. The kit comes balanced and includes main and rod bearings, and piston rings. Any reviews on these Scat rotating assemblies? Are they good quality? How fast do you think I could spin this assembly?
Second the heads, This needs to be a street car, so 93 octane fuel. I was thinking 72cc head which would give about 10:1 comp ratio according to scat. I was thinking dart heads. Specifically the 215cc iron eagles. (Spec sheet here) Are these good heads? Should I step it up to the 230cc heads? ($60 more for the pair) The disadvantage of the 230cc heads is that they require solid lifters.
What are your opinions on iron vs aluminum heads? Its 300 more to go aluminum and I do not like the idea of dissimilar metals for the block and heads (different expansion contraction, dissimilar metals promote corrosion/electrolysis in the coolant). So What are the disadvantages of iron heads?
That is as far as I have figured so far, but I was thinking edlebrock RPM intake, 700cfm 4-barrel carb, probably HEI distributor, possibly a MSD 6A ignition module, and I'm assuming a stall converter. I don't even know where to start on the valve train, I know nothing about picking out a cam, and I can't pick the lifters or rockers till I decide on the head.
A little extra information, this will be going in a 71 Nova with a 4L60E behind it.
Looking for any help and/or advise from the experts. Like I said this will be my official question thread and I will keep it updated on how the build is going. Hopefully with your help we will be able to make a sweet engine.
Thanks!
