Thanks guys! I wish I had an aftermarket block...

I've been hitting mine with 18.8 psi of boost and spinning it to 7,000 for quite some time on the stock block with factory caps and bolts and no fill. I'm betting you still have LOTS of room left to work with. I think the "myth" about how much these blocks can take is based on failed parts with bad tunes.

I agree. Look at a Windsor ford. Very weak looking compared to a 318-360 Mopar platform. Lots of after market blocks for the ford now but in the 80's and 90's lots of very fast stock blocks. As long as you keep a handle on the tune I think a turbo is easier on engine blocks and parts.

You`ve really got that thing scootin for sure...............

We'll see how good the stock block is in turbo form. I have some upgrades coming this winter that are really going to put it to the test in the spring.

From a lot of things I have read, a turbo is not as hard on a motor as N/A or other forms of power adders.

What Fast box are you running? And what RPM is it pulling thru the traps?

James that's awesome!

Lol... This thread is from 2013

haha, ya, but I haven't run the truck at the track since! I do plan on going in a few weeks to try out my fancy boost controller.

Josh: Thanks! Hope all is well for you there! I see your dad made the magazines!

Randy: I am running Classic FAST and pull 6,000-6100 through the traps.

Congrats on the new best as you have it running real good. I always wonder just how much the boost makes it pick up ? I mean if you took the turbo off what do you think it would run ? I am just curious of about how much the turbo helps as it seems many of the fast turbo cars I see have engines that are not all that heavily built and are closer to stock then I thought. It does surprise me how well some of them hold up under boost. But you sure have it running good. Ron

I would guess the motor makes around 350 hp. 389 cubes, M1, home ported Eddy heads (2.02/1.62), .520 hydraulic roller cam (wide LSA with 220 duation), 9.4:1 compression.

With the tight converter and no gearing with tall tires (3.55, 30" tall) I would guess somewhere around low 12's.
