I'm gonna go ahead and spoil the surprise as i need a little more push to help decide one way or the other...
Idea is basically to swap straight across my Gen VI crate or a freshly built 468(2 bolt block), Forged pistons (the ones posted in my summit link) forged rods, forged crank, my choice of cam & lifters, 049 open chamber oval port heads, Edelbrock RPM intake
(sorry george, that means no cheap take offs for you)
Cost to me would be head, intake & exhaust gaskets, and i'll have to buy the valve springs & misc if the cam requires different than whats on there now)
As i mentioned, i'd be going with a solid flat tappet cam, probalby one step below what kevin's running, as i want to run 3.31 gears and my 2400 stall.
Put yourself in my shoes looking the expense of working around the Gen VI problems in my block, vs trading for a fresh ready to go motor.
BTW... motor is balanced and blueprinted, all recipts, and has less than 200 miles on it, and i've seen it apart this past spring- this isn't a craigslist "could be good" deal... I've driven the car that its currently in, and even with the peanut port heads it has on it right now, it would blow my elky away hands down.
So should i keep what i have, and save my $$ for a long time and build the motor, or swap for this other motor thats closer to where i want, but maybe doesn't have as much cool stuff in it as my crate does?
