The 4300 definitely has impressed me, but I'm definitely not planning on blowing it soon. The last time the engine blew was 3 years ago when my brother floored it up a hill in reverse (I don't know why, and I wasn't there) and he blew a rod bearing. It rattled itself to death. But driving an automatic, and for a heavy truck, it kinda stays reving in one gear and not accelerating, but the truck starts to vibrate like it's pushing too hard.

 

the '96 doesn't have a rev limiter? i say go with exhaust because a blazer isn't a racecar that should be revved real high. the 4.3L only peaks at 5200 but shouldnt really even be brought over 4000. it's not a high performance motor and shouldn't be revved that high anyway.

 

Yeah, the only problem is I don't know when I'm at 4000 or even 5200, but yeah, I'm gonna get the exhaust. I mean, I have the money right now, I just need to decide which exhaust.
I made another post on what to get, Super 44, Super 40 (Which I've been hearing isn't so great) or a glasspack. Probably a Dynomax Thrush Glasspack.

 

Wait, you mentioned you ease up on the gas to shift? Sounds to melike your tranny is going out, dude. My Shelby had a bad transmission and it started with that and then got to the point where it wouldn't shift unless I eased off the gas.

 

A stick or auto tranny? I have an auto, but it's not so much that if I don't ease up on the gas that it WON'T shift, it just takes a long time to shift. Like it just hangs there overreving for a few seconds. The tranny is slightly new though.[&o]

 

An auto tranny should shift when it's supposed to, without over revving...that sounds like it might be a problem for you in the near future. A tachometer is basically useless in an A/T. I'd go with the exhaust.

 

Yeah, I've decided on the exhaust, but I made a new thread on what to get.
Super 44, Super 40 or glasspack.
I heard Super 40 isn't that impressive, and I know glasspacks are best on V8's, but I've never heard from someone with a Super 44 on their Blazer.
