Use the search function here, search 305 build, 350 build, etc, there's hundreds of engine combinations here.

I suggest 14" rotors w/4-piston calipers up front and a pair of 12" rotors x 2-pistons in the rear for brakes.

I have been WAY more scared stopping than I ever have taking off hard.

kennyhammond,

I don't think HE is into engines and things. These things are left to us.


Sorry I had to

Year One, of all places, has a dyno'd 400+hp 350 crate motor for $2989! You still need valve covers, carb, distributor etc. It's Vortec-based. The part that says to get a melonized distributor gear suggests to me that it has a hydraulic roller cam. The price is almost too good to be true, but I don't think they'd jeopardize their name on junk. Not a complete monster, but definitely scarier than the 305!

Sure, if the cylinders and rotating assembly are still ok. But tossing a hot cam or even just headers and a new intake/carb onto an old veteran engine isn't always a good idea. I think you'd end up spending as much rebuilding it as you would for the crate motor, plus you wouldn't have to worry about the new engine having hidden surprises. You can always void your warranty on the new one and build it up (I'd give it a try as is first). Read up on it via the web.

Starting with your 305. My project started like this.

Performer cam
Vortec heads Performer intake
3.73 gear
about to start exhaust with installing ,headers when one system fits.

The cam gave a little more power everwhere . Starting from the RPM it foot brakes from , made a nice revy difference. Sounds like a stampede of ponys.

The Vortec heads kicked all butt. Made the single biggest difference in power, but the original 305 heads were poor. A couple seals leaking did not help either. The vortec Performer intake offered nothing noticeable from the original. It still had a 2.73 gear.

The gear change to 3.73 gear with 28" 235/70/15 tire was welcome. The truck became lighter. Powerful footbrake smoke shows a plenty. With a 1600 footbrake stall, the truck torqued out of the hole like a bat out of hell.

My goals were to get the straight line acceleration of a mid 80's vette. C=D gave the 85 C10 a 17.7 in the 1/4. Some iPhone gizmo app claims it is now capable of 15.5 at 88mph. A LT1 auto vette when about 14.4-14.6. More work to do...
