482 Chevrolet Turbo-Marine

[earntaz]

Need some help with identification of some Big Block Chevy parts I have. Eons ago I did some swapping of Chevy parts and I wound up with a 4.250 stroker crank along with a set of 6.405 rods. The crank is forged and has a cast mark of 3521 and stamped M525. 3521 cranks were produced in the late 60s and early 70s from what I can tell. The rods have the name “Kiekhaefer” cast on the side with the number 621-3404 cast on the opposite side of the rod. The rods have been “worked” (polished, rough edges removed) with full float pin bushings and have an “A” beam shape similar to an FE 427 Ford connecting rod. The only reference I have come up with is in H.P. Books ... How to HOTROD Big-Block Chevys by Bill Fisher and Bob Waar. To quote them: “Chevy developed the 482 Chevrolet Turbo-Marine engines”. They go one to say that “Chev made 25 of these motors for Kiekhaefer and were destined for off-shore long distance racing and a few rods, cranks, and pistons were available for a short period of time”. This is a long shot, but is there any way of telling if these parts are part of that batch? The TAZ
