Crate motor vs. rebuilding DZ 302...?

[Xplantdad]

That's the ticket John...have a blast!

John,You should change your location to Foggy Monterey penninsula!

I wouldn't worry about an aluminum driveshaft. Sure, they look neat but the the cost per benefit is not very beneficial. They end up being so thick-walled to match the strength of .083 DOM steel tubing that it's just not worth it. Also the U-joint cups like to gall up in the weld yokes. Spend your money wisely elsewhere, like towards one of those brand new M-22 Muncies after the pain you're going to inflict upon your current M-21 with a new high HP/torque motor!

Thanks for the advice on that one Mark,I'll have to do more research I guess.

Jason,

Hey,we got SOME sun in Marina yesterday!

ever consider a 377 or an even larger big bore short stroke engine, it would rev like the 302. swap out the trans if its correct to the car or the crate motor may eat it up too.

I have considered that route as well.I'm hoping my M-21 will be strong enough to withstand the wrath of the crate motor.I may even send it out to have it re-freshened.

Well guys,pulled the motor out today and it's basically toast.Broke two rods and the cam in several places.It had already been sleeved in the number 1 cylinder.No failure there though.The bottom of the cylinder walls got pretty chewed up and the crank journels are junk.

So much for building that motor,huh?

My buddies and I are arguing whether to have a 302 built or just buy a high-hp 383 stroker.It would cost me the same either way.At this point,I'm thinking of just shelving the 302 idea for now and just picking up the phone.

383/550hp $6699

What do you all think...again?
