I cannot believe there's people trying to argue with Bondo!!! Follow Bondo's advice and you won't go wrong!!! (The truck cams are the same as marine)

I know! How dare they?!?



It helps of course that I agree with him too. At least in this case.

Re: 4.3 rebuild ?'s

One last question, I was reading in another post about putting vortec heads on, I have a line on a set out of a 1995 blazer for $50, my question is for the time being will the current 2brl intake manifold bolt up to the vortec heads because the motor the heads are on doesn't have a carb manifold

Re: 4.3 rebuild ?'s

Ayuh,... Unless the 2bbl. manifold is Also a Vortec manifold, No...

The manifold to heads interface is Very Different...

STOP!

The "vortec" heads were not intro duced until '96, so they were not on a '95 blazer.

However, GM has been using the TERM vortec since '87 when the TBI heads came out. That '95 blazer will have the same heads I am currently running with 6 intake manifold bolts per side and composite valve covers that SAY vortec, but they are not the vortec heads that people actually want. The heads you want will only have 4 IM bolts per side.

Re: 4.3 rebuild ?'s

I found a set of vortec heads complete w/ pushrods and lifters 3000miles on them edelbrock 600cfm 4barrel and edelbrock intake for 300-350...is that a fair price?

Re: 4.3 rebuild ?'s

Maybe????

Are we sure about the heads being true vortecs?
What is the PN on the manifold? 2111 you don't want any part of this deal, 2114 = vortec.
Assuming that 4bbl is an automotive carb, you CAN'T use it. Is seller willing to break up the set?

Re: 4.3 rebuild ?'s

the intake is a 4 bolt per side, i thought that was the tell tale well of telling if its post 96 vortec

Re: 4.3 rebuild ?'s

the intake is a 4 bolt per side

Good to go, what about the carb?

Re: 4.3 rebuild ?'s

carb turned out not being a marine carb just a edelbrock 600, the guy is offering me a cam w/ it but I dont know if its worth it or too big

intake exhaust
474 483
250 288
108 lobe separation

Re: 4.3 rebuild ?'s

LSA is too close.

I'd keep the blazer cam that's already installed.
