350 engine question
I have a 10243880...350...95-00...2 or 4...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal engine with 14102193...87-up...305/350......1.94"/1.5" valves heads and I want to know more about this engine as i am stuck with it for a few reasons. I have found out that this is supposed to be a crate engine from gm but it has truck tbi heads and not vortec heads as i originally thought. What would be the most reasonable way to swap out my old 305?? here is a parts list i came up with
Camaro parts list
1.350 engine with truck tbi heads
2.350 tbi unit
3. Not sure what cam
4. Full mac exhaust here weld metal EGR pipe to exhaust 844.00
5. Fuel pressure adjuster spring here 23.00 shipped
6. Better fuel pump here 100.00 shipped
7. 350 Electronic spark control here 75.00
8. B&M tork master torque converter
9. Rearend posi drum/disc 3.73 here 250
10. Tbi chips custom tune 100-300 here
All i need is some kind of cam that will work with the tbi heads to get at least 350 horsepower if that isnt possible than what heads can i get cheap to reach my goal? thanks in advance

A reasonable cam would be a LT1 take-out cam. You won't get to 350 HP with those heads, but certainly better than the 170 you've got now - perhaps 250-275.
Your link for the exhaust just goes to a "shopping cart" page. Worked for you, won't work for us.
Reasonable heads to support the ZZ4 cam would be http://www.sdparts.com/product/SD806...keHeaders.aspx . Not sure about the 350 HP part, but you'd be a lot closer.

Where are you getting the heads? If they are JY heads, you'll have to have them modified to handle that much lift. The ones from SD Parts I listed come ready for either cam.
