Take a look at these blocks GMPP is going to have out. I believe they aren't scheduled for release until spring '07 but, here are some pics and specs. The specs might not be completely right but, Robin is gonna post a spec sheet from SEMA!!!

Eh, thats a heavy pig and if it doesnt beat the Warhawk in price by a couple hundred bucks I dont see it flyig off the shelves, it is purrty, reminds me of my block

 

Well, how about beating the warhawk by a couple THOUSAND!!! Rumored price is somewhere around $2-2.5K.

The way I figure it is I have a heavy *** pig of a truck already so this block ain't gonna hurt it one bit.

 

Every little bit helps

If there is that much difference it will be like pacesetter and dynatech, dynatechs are alot better headers but the cheaper one sells 10Xs as many.

I would probably get the GMPP one if it is that much cheaper

My 4.100" crank and some 4.25 pistons=464 sounds like fun but I think I would have to go to 4.500" stroke and really have some fun

 

 

I don't think it's gonna be a Pacesetter/Dynatech thing with these two blocks though. I guess we will have to wait and see.

4.5" stroke will only fit in the tall deck(9.7") version which will be released later.

 

I would go with the tall deck version to make it worth my while to upgrade from y 418.

As far as quality it has been my experience that you get what you pay for but we will see once these hit the streets.

 

<-------- Waiting for March. 4.25 bore x 4.50 stroke = 511ci.
Plus more head studs, provisions for 60mm roller cam bearings, better oiling, and alot of other fun stuff.

 

I bet a few people could benefit from the 6 bolt per cylinder arrangement

 

<----------------------------------tis out of this mans budget. but it's nice looking
