Any swaps?

[bestof1999]

In Need of any ideas for a swap for a 1999 GMC Suburban 5.7l. Cant Cost too much. Wanna stay Gas and wanna be getting around the same Mpg's as the 5.7

Yeah 5.7l vortec lol. But really its your best bet cost wise. Maybe 383 stroked vortec, they can be had for around $2500. Either that or go LS, if your good at shopping and fabbing/wiring then it can be done for around the same money.

I've heavily considered a 6.0L swap for my truck several times but I can't justify it. The 5.3L and 6.0L might make good power but it's not down low. I've driven a few and I'm not impressed. The 454 and 8.1L are out there too. Is your Suburban a 2500? If it is then a 454 wouldn't hurt. If it's a 1500 stroking your 350 out to a 383 with some head work would be a good option.

Its a 1500 but i dont have over $2000 to drop into it right now. Thinking just a stock replacement

Not much you can do with that budget. I'd say just save up for awhile

For $2000 you could get another Vortec 350, used from a junkyard, get everything squared up, freash bearings, small cam, and the heads rebuilt. Some porting with bigger valves and a tune. But if your engine is fine I'd leave it alone.

Its Got a Spun bearing waiting to get it opened up. Just planning incase my block is grooved. I can get Remanufactured Engines for under that too

Any advice on Holley stealth ram conversion greatly appreciated!

The best deal I think would be a L31-R and just swap it out. Or if your doing the work yourself rebuild your current motor.
