Exhaust manifold outlet diameter?

[RustyRatRod]

I put my order in today for the TTI 2-1/2" exhaust system to bolt up to the /6 exhaust manifold, $622 including the $138 UPS wants to haul it across the country!

I will "improve" the exhaust manifold with some grinding when I put the 2 bbl Holley 350 on. Haven't decided yet on pulling the head off for further porting, and new seals and valve springs and cut it about 0.080" or so. Might as well do it all at once!

And I'd like to put in an RV-10RDP cam while I already have the engine apart. Surely it'll need a new timing chain assembly. And a baffle in the oil pan, maybe a crank scraper, port the oil pump passages.......

The oil pan baffle(s) and crank scraper are way overkill at your power level. I wouldn't worry about it.

Hopefully, you ordered it straight from TTI and not from Mancini.

Yes I called TTI and ordered it there. They said about three weeks for delivery.

Good for you! I called Mancini and they flat LIED and said they had it in stock. The feckers.

good to know, because if I decided to go that route they would be who I would potentially go through....
