Check you sender ground 1`st. Black wire that bolts to the car underside somewhere.

Total ground = empty.
NO ground = full, to past full.

That should get you 550 to 600 hp if all is good in your parts selection.

I believe the `75 is the oddball. `76 and `77 carbs are some of the best ones.

Check for crap in the bottom of the bolt holes in the block for the head bolts.

Also, have the heads been milled a good bit?

My `71 T37 was 3660 a while back. With me in it. Iron heads, aluminum intake with headers. A/C compressor gone but, had the rest of the system.


455, t400, 12 bolt. Full interior.

What Paul said above is a budget way to go. 068 with 1.65 rockers. That will give you .448 lift. With 212/225 at 050, that will be a decent step up without going to big valves and screw in studs.

There were 15 heads in `68 also. More like a 75 to 78 cc chamber.

At the very least, I like the wider bolt spacing on the center ports on round ports.

And, how many pontiac factory round port engines run worse than the d port counterpart? Even the RA2 with it`s...

I would use straight 30w oil and a bottle of gm eos for break in. Change the filter only after the 20 to 30 min run in time. Then, add 30 w to full mark. Then, run engine with break in "package" for...

I have not lost a flat tappet cam. But, in the last 3 to 5 years? Nope. My a$$ would tighten up a bit if I were to do it today.

Run your factory crank, IF it checks out. ARP main studs, 4340 rods with a good full float piston, and you`re good to go.

I wouldn`t sweat that at all. Use your factory caps. Get some 4340 rods, a good set of full float pistons, AND a good balancer/flexplate. All balanced, of course.

I agree. That`s why I added the old school poncho to the discussion. The oil doesn`t "cause" a leak. But, I would use caution when adding to a higher mileage engine when that engine has had regular...

That`s a "Trans Am" block. Paul prolly tapped those bosses to be able to toss it in any chassis. I don`t think the 557 block even has all the bosses like the XX block.
