Hey Guys, it been a long time but happy to be back,
I probably ask this once before, but here we go again.
I have a 411 swap with a marine intake and wipple S/C on a tahoe, also swap a 4L80 with the 14 Bolt Disc brakes.
I undecited to re built the 5.7 or just swap a LQ9, any thoughs? I dont have to worry about the smog legal stuff.. but want to keep it Fuel injected so I can tune it With EFI live.
Thanks for the input!

lq-4 or 9 and a whipple. Simple, reliable and many available.
Sell your current setup or par it out and still be ahead of the game.... I would have done this and been happy but I'm already in too deep with a bigblock....

Welcome back.

Normally I'd say go with the Gen 3 engine if you had a stock fueling system because we all know the stock fueling system is crap and at its limits on the showroom floor. But as you've done the marine conversion, have the Whipple already, ect, you might do just as well to pull the long block out and slide an 8.5 to 1 383 or 400 in. It would be far cheaper that way. The cube decision would need input from the SC crowd, and they'll need to know the size of the Whipple for that.
