Pics... 3500 crank with 7x timing wheel

[Driver_10]

I just got my crank back from Mark at TCE (A.K.A. CNCguy) and the work looks great. I had the crank snout machined to fit the double timing chain and a new 7X timing wheel fitted onto it.

The next stop will be knife-edging. The final balancing and regrind will come AFTER I get my modified, "H-beam", "small-journel" SBC con-rods back from Mark.

My progress is slow, but Im moving along. Enjoy some engine porn in the meantime

What Marc needs to do is get a couple of these on hand, make said modifications to them, and then sell them with an exchange. Would probably be a pretty popular item.

Is it standard stroke and bearing size? Looks good.

The rod-journels are going to be re-ground to 2.000 and Im going to use modified 327 "H-beam" rods to finish the combo. It should be good for 600hp crank.

600 crank?
Holy crap. Are the mains gonna be able to hold up to that?

Im using a 3500 "cross-bolted" block for my camaro. The oil-pan is a thick casting which bolts onto the sides of the mains like a girdle. Ive seen regular 2-bolt main 660's survive 500 crank w/ "cast-iron" main caps. The 3500 uses steel main caps with thicker material. Im also using ARP mains-studs with the stock stamped windage-tray as reassurance.

dude that engine is going to be a work of art


you are realy thinking this through and it shows good job man

[Driver_10]

I dont want to ever loose another engine to an "oversight" or a bad "mis-judgement". I toasted my prior 3400 by not being careful. (3400 swap R.I.P.)

Very nice! One of these days I'd like to finally tackle a build like this on my car. Still running the stock short block for the time being. Can't wait to see how yours turns out.

What happened to the 3400 for it to grenade?
And how much power was it pushing?

[Driver_10]

It wasnt the power output, it was an over-rev that killed it. It touched 8000rpms on a missed shift and the valve-train gave up the ghost. I couldnt tell you how much power the engine made off-hand.

Id have to guess that it was in the mid 300ish range since I was only running 10lbs of boost.
