Your in smog restricted Cali. I would find out what is legal for you, my meaning is any and all mods need to be 50 State Legal for you to make any changes because the smog police will kill you otherwise.

13 seconds is a nice realistic time attainable with a 350. That being said, it'd be pretty hard to do it with that tbi setup and stock heads. I'd carb that sucker with a Holley 670 street avenger, Edelbrock Performer RPM or RPM Airgap intake, Vortec heads are pretty cheap and flow decently for what you want with some mild porting, maybe this cam http://www.summitracing.com/parts/CCA-CL12-211-2/ or something similar, stall convertor, and gears. I think that'll get you there. If cost isn't an issue, I'd probably go for a set of Dart Iron Eagles.

Thanks for the input am even thinking of putting a bigger piston making it into a 355

For about the same price you would have in a reman'ed set of vortec heads you can get a set of Engine Quest (EQ) heads. They are cast in the same plant that cast the Pro Action heads before RHS bought them out and use the same molds as RHS did before they dropped their line of cast iron heads this year. For a mild 350 I would use the 180cc intake runner head. You may could get away with a 200cc runner but you would start to loose low and mid range torque with that size runner on a mild 350 ot 355.

The 270 Magnum by Compcams is a good cam but it is also 30 year old cam profiles. I feel you would be better of using something like the XE274H or if you are going to punch it out anyway Replace the dish tops with a flat top and run the XE284H. If you have it in your budget to upgrade to a retrofit hydrualic roller I have used the XR288HR with very good outcomes. It maybe a little more then you want if you are runnign power steering and power brakes tho.

Also none of these cams will work well with TBI nor will you ever see the potential of a SBC with factory style TBI. Like was mentioned before the RPM air gap is a great instake for mild street engines and the 670 street avenger is a great street carb.

If you are going to bore it .030 over to make a 355 I would strongly suggest upgrading to atleast a Hypereytectic if not a lower end forged piston like the Probe FPS. You can also get rotating assemblies with Hypereutectic and Forged pistons really reasonable now days.


Here is a video link to the 350 I had the XR288HR in. It was a stock LT1 out of a 95 z28 I converted to carb and installed this cam in.

You can run a flat tappet. Just make make sure you use the right oil with ZDDP or it will wear out the lobes on the cam.

Ok well you guys can cover the engine stuff.

If you want to go faster you also need better gearing. This alone will make the biggest difference. If your truck is all stock it prob has 2:73 gears or 3:08s with that kind of gearing even if you have a strong engine grandmas Camry is still going to be tough to beat at the stoplight. Next you need a higher stall converter. And the shift kit. If your truck is a 700r4 also pair that with a corvette servo as well

And I agree but I have to first get the engine going so I can find out what kind of stall to get.same thing with the trans kit because then I can adjust the trans to the tire and power am making.But your right after am done with engine ill be asking you guys for gearing advise

You can't adjust the transmission like that. Only build it to handle more power. And only one way of finding out when it's not good enough. But yes once the engine is built then decide on the stall. But 3:55 and 3:73 gears with a posi are what you will be looking at

on a 87 chevy c10 what is the number of teeth on flexplate? it has a 350

[Rannos]

Pro Topline heads are great heads and the XE274H cam is a decent little stick. Your valve size should be 2.02 and 1.60. You will need a new set of rockers as the slot in your stock rockers isnt long enough for the lift of the cam. I would suggest doing a 1.6 full roller rocker but 1.5 roller rockers are good to.
