OK I am starting a 351 fox swap and I've seen before that you can use your 302 upper and just replace the lower.I have a TFS Track heat upper but I hav'nt actually seen a lower for a 351 that says it is for this upper but I did see the one at Summit that is for the R-Series upper has anyone used this will it bolt up or am I missing something?
 
Unless someone here has direct experience with this, I'd say you need to call Summit and ask. They have great tech support, and I believe they actually now own Trick Flow.

Yes, it is true that some intakes came with the same upper for both the 302 and 351 engines (the GT-40 is a good example), but I don't know that the 302-based Track Heat has a 351 counterpart.
 
there's only two upper intakes that I know will bolt to a truck lower intake.
one is the GT40 from the lightning and the one that the saleens used. I forget who made them. systemax??
 
I think this is a whole assembly. I was thinking of using this intake on a 351 fi
Edelbrock.com - Manifolds - Ford - Victor - 5.8L
Doesn't that list #3886 as the 'base only'?

I'm pretty sure all of these guys (TrickFlow, Edelbrock, etc.) will sell just the lower you need.

Skip talking to Summit Tech line guys... :notnice:
Call the company tech line directly....



good luck,
