Stroker question

Jstang85 March 3rd 2014, 3:16 am

I have eagle H beam rods 6.60 length and forged speed pro pistons .060 over and I was wondering if I could run a stroker crank with what I had and if so what would be good.

you could stroke with those parts if you had a 429 to start with to a 460

Actually no.
If the pistons were from a 3.59 stroke then the compression height on the piston is made for that stroke. Likewise for the 3.85 stroke. The pistons will need to be changed.

Thanks for the help

Did you know that flat top forged 429 piston were cut for use with a 460 crank?

Those pistons would need to be cut down .130 which is possible but is that really a stroker?
If you wanted to stroke a 3.85 to 4.3 by only cutting the piston it would need to be cut .225 so that isn't feasible.
If you go 4.3 or 4.5 you want a longer rod with a lighter weight piston.

Back in the day I think shaving a TRW 429 piston down to use in a 460 was about the easiest way to get a zero deck flattop piston for a 460. If I remember correctly FPP used to cut/sell them.

IF you read my first post, you might understand about stroking a 429 to a 460.

ANY other. no , that means no it won't work

What crankshaft throw JOURNAL size are the connecting rods meant to use...?
