Can some one tell me if a TBI 4.3 exhaust manilold..will fit on a 4.3
Vortec cyl. head..mine has a crack on the drivers side.it's gonna be a
job to change...probably have to take it out throug the bottom...because
of the steering...also the power steering bracket has to come off...not
to mention breaking bolts! Appreciate any advice.
Should fit, however if it is a used manifold it may not fit as they tend
to warp (that is why a lot of them are cracked). My 94 had both broken,
the DS right behind the steering shaft and the PS was snapped just
behind the first mounting ear. I ended up pulling the top off the engine
because of rusted bolts.
The mistake that many make is over tightening the because it need to
float a bit on head bfor expansion and contraction. One that crack,
crack because they cannot expand and contract properly not because
they warp. (they can warp or crack from biult up stress though if they
cannot expand and contract properly)
