I'm building up a 2 bolt 350 block, .030 over, stock rods and crank, Speed Pro/Sterling H345NP30 pistons, and Comp XE268 cam (.477/.480 lift, and I got the whole kit, so I have matched springs, etc). I'm going to be getting the comp roller lifters, too. Intake is Performer RPM with a 600CFM Edelbrock carb, stock mechanical fuel pump. I'm bolting up the NON-Torque Step Hedman shorties with the matched Y-pipe going into a gutted cat and out a Hooker Aerochamber catback. That's basically everything I can think of, but if I forgot anything, lemme know.

This is gonna be a daily driver, so I don't want to go absolutely crazy. I want something with good low end. Not worried really above 6K-6500 RPM. I'm looking to peak between 350-375HP. I wanna keep it around $800.

 

I would contact World Products and let them know of your situation. They're pretty good at helping people out.

Hope that helps.

 

I know. I wanted to see what you guys had to say first.

 

You might want to look at a bit larger cfm carb there. Or buy mine. Cause I was told by Summit that mine is a little too small now.

I've put the figures into the formula, and at above 5k rpms if I recall, we need like a 670 cfm carb, if I recall correctly.

 

I figured as much. I do have a double pumper Holley 750 here. Just REALLY needs a rebuild. But I'm more worried about heads right now.

 

Here is a cylinder head shop in NJ that should be of some help to
you.

If only for info

Might want to talk to them for some professional advice
or some work.

 

Im going with the mod. vortec heads from sdpc. There under $700 and should run very well right out of the box. You need a dedicated manifold, but if your going carb you can get the for under $150. Powerhouse has one that is designed for the heads. I believe it runs $130. Its not just drilled to bolt up, its actually port matched(well as much as you can expect I havent seen one myself) to the heads.

 

So, none of you guys run anywhere near my expected mark?

 

I wish.

 

Mine reachs the mark if you sell the intake for $100 or so. That carb may be a bit small for 375hp.

 

I WOULD GET YOUR 750 DOUBLE PUMPER, PUMING LIKE NEW AND PUT THAT ON THERE.

 

id say go with the vortecs, ive heard a lot of praises on them, a little porting wont hurt, and you cant go too crazy with the springs out of the box, but besides that they make awesome power, although you need to spend a little more on the model specific intake..

just a thought

 

The vortec heads from sdpc come able to accept .550 lift, though I wouldnt push it, and you can have them tapped for screw in studs which is highly advisable if your running a cam with lots of lift.
