It's getting time for a new engine in my 80 blazer and I don't know if it would hurt to have more engine when I normally do the mud. The stroker was great in my Camaro as a kid, but now that I've grown up is it still a good idea?

Ask muddin how much she likes her stoker in her Blazer... she loves it! And it is pretty sweet.... she made a video of her peeling out and I think most of the guys who saw it wanted one after that.... :)

The stroker is the way to go you get so much more torque than a 350 and they can be built to make much more horsepower they blow away any 350 I've ever driven.

What ever you decide make sure and get a GM crate motor. The 350 one is the cheapest. Thats the one I have in the Jimmy (250 hp) With 4.56 gear and a mini spool I can do a burn out with both rear 35" MTRs :D

383 stroker (http://www.bluefox.tv/~iroc/smokage.mpg)

It doesn't even bat an eye at smoking some 33's. I've still got grooves in my tires from that burnout. :cool:

It produces enough torque down low for crawling, then produces enough HP for mudding. I wouldn't go back to a 350 now that I've been spoiled. :D

It's a real easy swap too. The only things that won't bolt up that are from your 350 is the balancer and flex plate/fly wheel-you would need to get ones for a 400 crank.

Stroker, definitely. Especially for torque and power, they’re great for 4X4's.:nuke:

I still wonder on gas milage... How much of a total change are you 383 people experiencing? I've never built one with milage even a consideration LOL :p

I actually get better gas milage than I did with the stock 350. And the 350 I replaced only had 45K on it.

On the highway I get 13-15....depends on which way the wind is blowing :)

Cool deal Mudd'n. I have been tossing the idea back and forth along with what to do about the FI. Go a custum port setup with a Haltech ecm or who knows. I guess we will see, I just know this spring when the 4.56 14B FF heads in and I upgrade to 37's or 38's I'm gonna need more power and milage just to equal the bad power and milage I have now LOL. :rasta: :D

there is no replacement for displacement! 383 all the way, make sure you have it balanced.

i would build a stroker.

definately go stroker. For us here in snow wheelin' country it's handy to build the 383 instead of a big block to save weight. Sure you can get more torque out of a big block, but one of my friends has built his 383 just shy of 500 ft-lbs of torque and 450 hp for his blazer. Not bad I'd say!!! If I built one I probably wouldn't go that hot since I'd like it to last a little longer.
