quickd100 » Mon Jun 24, 2013 8:23 pm I built a .030 over 440 for my bosses 83 clubcab about 15 years ago. The build was KB hyerutetic pistons with the quench height set at .035 from hitting the heads, (452's). Used the MP porting templates, bronze guides, stock size valves. We used the .474 lift MP hydralic cam, street dominator intake with a 850 thermoquad. 1-3/4" truck headers and 3" duals. Compression is measured right at 9.4-1 and it run great on 89.5 octane pump gas. Behind the motor is a TA 10" convertor and a 3.55 suregrip.
It runs like a scaulded cat and care is needed if you hammer on the throttle at lower speeds as it will go up in smoke and try and swap ends on you.
The cam you have will work just fine at either compression ratio, you will want a good convertor and 3.55 or deeper gears to get the most out of the package. I can't say enough good about the 10" Turbo Action convertor, it's rock solid reliable and you will find if you install one that it will be the single biggest performance improvement.Dave
moporridge » Sat Oct 12, 2013 8:06 pm A friend of mine also had a set of hardened seats put in the 516's and they leaked. On my moho 440 I just milled my 452 heads .060 and ran the Fel Pro .020 thicker than stock steel shim gasket for a difference of .040 all together. I then ordered the rocker shaft shim kit package to raise the rockershafts .040 for the correct lifter preload. Engine has 284 purpleshaft and runs like a bat outta h*ll. Dont be afraid of milling them.060....the Mopar engine book recommends this for a compression increase. Just be sure to run head bolt washers. Also check intake manifold fit anytime milling is done...it will usually require shaving if heads are milled .060.
