6g74 route

Love the sound Dude. 272 have the best lope I've heard. Like the sound of the exhaust as well. Once you dump those rich spots your in for a surprize.

Well....I am looking forward to tomorrow then! cleaned up the map a bit....will be going for a spin and seeing how she goes! bit of on road tuning for sure.

Exhaust was made in my earlier days when I didn't really do research into anything, just wanted things to be done....mandrel bent engine pipe, 3" high flow cat, 2.5" mandrel bent from cat back, then 2 x 2" press bent from the rear axle to two mufflers. Never sounded better though...
Will let ya's know how it goes tomorrow. Just hope that oil leak was the rocker cover ><

within the last week ive been noticing a real loss of power with my 6g74 around 2k-3k almost like the car bogs down and the rpm needle doesnt move up as fast. I'm totaly baffled as to whats going on here, really hoping you guys can give me some insight on what i should check out.

How's your oil pressure?

[jessecain1]

idk, how the oil pressure is couldnt get the damn gauge to work

[TUFFTR]

Only aftermarket gauge I have running right now! Very handy to have....a 5psi drop alerted me to an oil leak...

Lots of these 3.5 swaps fail because they are running a stock 3.0 ecu. It seems that the timing is too far advanced and it causes the engine to kill itself. Mine did it in my satin black car. Spun a bearing in only 3000 miles.

whats a remedy to this problem?

is this just a problem with 74's, or are 72 strokers prone to this too? and yes, what's the solution (other than AEM)?

[jessecain1]

at this point im really hoping i just need to clean my iac

If you have a 91-92 CAS, you can try adjusting your base timing and then log it to make sure you aren't knocking. For 93+ models, you would either need a piggy back timing controller like an emanage or swap to a flashable ecu. You may even be able to find an ECU that matches the engine if you search hard enough.
