Ford 352?

[Bench Racer]

Thanks Ken: I found the 352 in the NHRA spec's. (2010 Cobra Jet) Looks like they made a good choice too. 352c.i., EFI, 3.40 stroke, 11.25cr, 56cc chambers, flat pistons, .005AB deck, 2085/1605 valves, 285hp/NHRA factored 289 in an auto. The NHRA blueprint says throttle bore (4@ 1.75)?? I assume that must be an EFI that looks like a 4 bbl. carburetor?? If the 1.75 is inches of the bore, that is 44.45mm x 4=177.8mm?? Help me out here Ford guys lol, I'm familiar with the Chevy LT-1(48mm x 2 throttle body) If my logic is sound this Blue Oval should be a rocket! I saw online where Nick Morris ran .995 under at Bowling Green! It ain't no slouch. Nick loaded my brother at Indy in 2011 for class, I got to talk to them in the staging lanes, Nick,his family, and his car are a class act. Don Jackson

This is not an fe motor, the both use an 8.2 deck.block with a 3.4 stroke just different bore size.....

Nice meeting you this weekend Craig, you have a nice piece.

Thank you....the 347 that street racers have built for years is a .030 over 302 while the 352 is .060 over and both have the same stroke.

Maybe JHeath should read up on his Fords before he spouts his words of wisdom again.

Yep, street racers can do a 347 with the stock block at 0.030, but going to 0.060 is a risk unless you do a sonic check.
So, the reason why Ford racing used the Boss 302 block to go 0.060 and why they call it a 352.
Heck, they could have used their racing blocks with thick walls and go 4.080 and call it a 355 or go 4.100 bore and call it a 359 or go 4.125 and call it a 363.

The real point here is that the 352 buildup is what it was accepted by NHRA.
