Anyone know of any combinations that suit this engine? Anyone ever happened to rebuild one of these up... I have one that has just been magnafluxed, align honed, bored to .30 over and new brass plugs cam bearings, etc...
1. Is 350hp possible with this engine
2. Can I throw a carburetor on it just by changing the intake manifold??
3. Also, I was thinking about some vortec heads??
Any thoughts are welcome, thanks fellow hotrodders, btw, this engine is for a '71 chevy truck...thanks.
just rebuilt one bored it 030 over deck it used a small custom hyd roller cam and used the PBM heads on it it went back to TBI for a stock gm truck
need numbers please though bro...thank you...
what numbers ?if you use the TBI you have to run a small cam need to idle low for the computer to work K code.if you going carb there is many cams to pick thru the heads are the PBM heads for the 87 intake and not vtech you can get them both ways you can build it like any sbc 350 hp should not be hard with the vtech heads
Is this a roller cam block? Probably not, just thought I'd ask.
yep it should be but they never used a roller cam it was flat lifter hyd in the trucks.i done some:D
no roller...or at least no spider setup
but the block should be drilled in front of the block for cam trust plate and towers for spider ???????????/Quote:

You can achieve what you want with the stock TBI heads but they will probably be limited/struggling to make 350hp and by the time you got them work on you could of got you a better set of heads to reach you up to 400 hp. TBI heads SUCK ,or really dont suck , air flow is restricted. I use the TBI set up for staying at low rpm and low end torque, I got a heavy vehicle that sees a lot of idle time and probably never above 4000 RPM. If you just want to start your build with a "TBI" short block , the TBI really means nothing. Its a great SBC block.
indeed...just letting you know that it was a tbi motor that i plan on using vortec heads and carb on....need some opinions on details of setup
Any small block set up will work with that block. You can even stroke it. There are probably a couple hundred variations. What are you putting it in? Whats your intended use for the vehicle?Quote:
