Target compression ratio A/J

Wait!
Are you saying the cam has already been ordered?

Are those aluminum heads closed chamber heads? If yes, then IQ52 has got a recipe for you in post #6.
But if your cam has already been ordered, And with Scr of just 10.15, Your Dcr may get to be in the basement. This SCr will take a fairly mild cam to be a fun streeter.If the Dcr falls too low, you will be wanting a higher stall TC to get moving.Low DCrs tend to be soggy out of the gate. Aluminum heads suck heat out of the chamber. Heat that coulda been used to propel the vehicle. This lost heat needs to be compensated for with about a half a point of Dcr. This may take additional Scr to get. So if your cam is already on the way, you may have gotten ahead of yourself.
But if you are building a track engine, then this hardly matters cuz your hi-stall TC is gonna blast your car right thru and past the soggy bottom end.

If I had a BB for my streeter, I'd want to run 3.23s. and a stock-type stall(2200 to 2400).And that would take a strong bottom end torque supply. And that would mean a conservative cam,and a matching Dcr.In this way, first gear would be good for close to 60mph, and 3.23s puts hiway cruising on the table. I would run a small vacuum secondary or AVS-type carb that I can bring the secondaries in as early as I want to, or as late as I need to. A double pumper will just destroy the tires. A spread-bore would be even better.In this way, I would attempt to not blow the tires away on every hard take-off. As a streeter you don't need a big cam, cuz there's that speed limit thing about 5 seconds after take-off.So you can't use second or third. And a 7000 rpm redline is kindof crazy if you hit 65 at 6000.

Closed chamber 84 CC. I have not ordered the cam yet, havent heard back from cam builder yet with his thoughts, this engine Ive decided is gonna go in the 6000 pound 4 wheel drive truck I mentioned to you, Im gonna put the 340 in the 2 wheel drive.

This trucks has a 4 spd with granny gear, I gave what specs were asked of me to the cam guy. hes the one that suggested target zero deck ( if I understood correctly )

One thing that Id like to know is why does the story change on whats first, alot of people say cam is first, other people say other things. Why cant everyone get together on this one?
