I don't have the 62" mm TB yet. I do have an air raid power aid on it. How do you think the AW4 will hold up? My I injectors are at 41psi, will that also hold up and feed enough fuel to the block

Your transmission should hold up fine to the stroker. Are you certain of that reading? Fuel pressure should be 49psi +-5psi

I've used the Transgo Trans Kit 340-HD2 with good luck. Order off ebay. Best if installed by a trans shop and have them change the filter and flush the fluid.
Will probably need 24 lb injectors and your ECU tuned to make it run well.
Contact Ryan at FlyinRyanPorting@gmail.com He will be able to tune your ecu.

Also Harland Sharp at Summit S4096 $331.
The roller rockers make it smoother and quieter and give more consistent/accurate 1.6 ratio.
The trans kit makes the shifts slightly quicker and firmer. option- to be able to have trans stay in 1st gear when lever in 1-2 and not shift into 2nd.
Both are good upgrades.
Roller rockers are easy, just like stock install.
Auto transmissions always scare me and I have a trans shop do the install. It doesn't look hard or tough but I would hate to screw it up.

The Harland Sharp roller rockers will smooth out the valvetrain noise but they supposedly only last maybe 40-50,000 miles. The Yella Terra rockers will outlast the rest of the engine if you go with those but their around $200 more than harland sharps. The trans kit isn't absolutely necessary but a lot of people say it makes the shifting smoother.

So the machine shop is done with my block!! They cleaned the block, magna fluxed the block, honed the cylinders to 30 over and fluxed it again. Ground crankshaft (258 4cw) to 10-10 and Installed the cam bearings. 361.51 is my total today. Ready to bring it home!!!

The transgo kit is rather affordable at 100.00 mostly. The roller rockers, am I right I
Going to need a taller valve cover to fit them in

whats your input on an after market oil pump? High pressure versus high volume....
and on another thought would you also recommend a higher quality oil.?
