Our new timing covers are machined tighter than the low spec for a GM cover. The blueprinted assembly comes with a booster plate and adjustable pressure regulator and we hand port and polish the oil passageways in both the timing cover and the oil pump cover.
Oh wow! That doesn't sound half bad, especially since it includes a new cover. Always great to have multiple options!
TA makes good products. I'm aiming for people looking to appear stock or use date coded parts. Both will make for a strong 350.
