question about port and polish

[93v6firebird]

how much in general do you guys think it would cost to port and polish the TB, heads, and intake manifold?? as well as a 3 angle valve job? please itemize the list, instead of a rough total... thanks a lot!

I'm in the same area, so if you find out what needs done exactly, i'll go around and price some stores around here. I'm only like 30min from DC right off I95.

I just had my lower intake ported and polished and it was $125. My heads were $569 which included before and after flow charts, Stage 3 competition port and polishing of intake and exhaust runners, match port intake to heads, match port headers to exhaust ports, hot tanked the heads, 5-angle valve job with a little backlash on the valves. I have the modified 3.4L intake with the LT-1 TB which I bought used for $350. I know this is more than you were talking about doing, but it should give you a rough idea. I would imagine that the heads would run about $350 for a basic P&P with a 3-angle valve cut. The intake should run about the same and I don't know how much the upper intake or TB would run. Hope this helps.

about how much of a gain would I prolly get for the 3 angle valve job, P&P the TB, and intakes? and maybe the heads?

I'm right there with 93v6firebird.... I hear of it being done all the time but from what I've seen, it doesn't make a huge difference unless you're preparing to run boost or nitrous...

I would imagine the bennifits are less drag on the engine (some freed up hp..), improved durability..... someone fill in the blanks here!

Well, the casting on the 3.4L heads are the same as on the old 2.8L V6 heads as well as the intake so you know that the 3.4L is pretty choked off. If the head adn intake work is done right, but a good machinist, you will tell very noticible gains. I think Tiago can back me on this one...maybe.

I called some people like I told you I would. Except we never seem to be on AIM at the same time, so I'm reopening this thread. Anyways... From the info I've gathered the closest place (to me) that does a "true port and polish" is in bmore. A place called Lads and here's the number I was givin. 410 799-1763. I havent called them only cause its long distance and I'm already expect a big cell phone bill :/ I was told that nobody around here does it, but if you happen to find a plave that says they could, they're lieing and you shouldnt let them touch your engine. Also... I was told that Lads's estimates on time are undershot, "if they say 2 months, dont be surprised when it takes 4". This is all I could dig up. Sorry if its not what you wanted.
