Up Grades on Stroker-Suggestions

Mechanical flat tappet. Spend the$$$ you save on a roller on different things. If your going with a converter from the USA then I'd suggest PTC converters.

Also been told to contact either Lenny at Ultimate Converter ultimateconverter.com, or Dave Caine at ATI atiracing.com . Anyone used these?

Your cam is limiting you even with stock RPMs and that intake. You can get significant gains by replacing just the camshaft. You are really only opening the intake valve about .485" and the heads only flow around 235-240cfm and the you have a big intake on top of that. If we work backwards from that 400NM (296 pound feet give or take) to the tires you're not making anywhere near the "2hp per cfm" general rule. Replace the cam with something in the 250° @ .050 and at least .580 lift before lash and it will wake right up. I don't see anything else that is glaringly "bad".

Yes the intake is a limiting factor thats why I spent some time modifying the 450 Holleys
Cam is old school as I'am. Been told that a duel patten cam would be the go, can you point me in the right direction?
Thanks

Whatever you do, it's not going to be cheap..

Yep I understand that that is why I want to plan this better. When I change the cam I will also get a converter to match.

That 528 will easily push a decent SB car to a 12.00 timeslip, stroker or not. Lash it tighter, like .020-.022 area. An XE268H will get you a mid 12 in a decent car and the 528 is miles bigger from a duration standpoint. Take ~ 320RWHP to push a 3300# car to a 12.00/110.

The intake is a huge question mark. If it's as cast, it's not a good piece. With the requisite mods, pop sticks/epoxy, it will work well.

A better exhaust system wouldn't hurt. tti or a 1 3/4" tube, 3" and ultra flows.

A good converter could show a .5+ gain in ET alone.

Rob you havn't lead me astray yet so I will try the reduced lash. The intake is as cast as far as I'm aware, I will try to research the mods you are talking about.

Thanks
