Is this cam too big? Like the title say I was wondering if this cam is too big for my setup. I have an lq4 with 317 heads. I am puttung a prettty big turbo on it with a blow thru carb. It is going in a foxbody mustang primarily as a race car. I plan on replacing the crank, rods, pistons next year but I was wondering if I could squeze this cam in with the stock pistons for this year. Any help or suggestions is greatly appreicated. Thanks

Not so sure that would be a good idea. The cams I see that go into turbo cars are around .216-.222 and .544-.569 with a 116lsa advanced around 4. Your honest to god best bet is to get in contact with a sponsor and give them your details. They will more than likely be able to help you more than any of us.

I guess those are the kind of reponses that I was expecting. I wasn't really looking for anyones opinion on how they think it will work but if it will hit the piston. To me .651 lift seems to be asking alot out of a stock setup but it does have a dished piston and the 317 heads are pretty big so I was hoping I might get lucky. Was just wondering if thee was anyone out there that has run something similar or knows how big I can go before it becomes a problem. I don't want to get into fly cutting the stock pistons or buying 2 cams. I already have a set of Diamond turbo pistons but they require a 4" stroke and a 6.125 rod. Spring is just around the corner and I was thinkin about trying it out with the stock bottom end and rod bolts just so I could make a couple passes.

The Stock dished pistons won't help with ptv. They still have a raised edge around the outside. Your intake valve will still hit there. Only way around it is to fly cut or get a different piston.
Not saying your cam won't fit because you need to mock it up and clay the piston. Only way to be sure.
