3.4/3500 engine

[shrek]

hey: After reading a while on here i understand that the 3500 heads and intake are the way to go for a little performance on a 3.4, correct?
I have a 95 Camaro with a 3.4 that i would like to upgrade a little but nothing
exotic.I know this may have been asked but if the 3500 is the way to go,what vehicles hanging around the "RECLAMATION" yard( man what a word,they don't even call them junkyards anymore) should i be looking for?
Also i understand a cam and headers would be good too,any good recommendations for both in a hi po street application. Thanks for any help,I realize that these questions may be repetative but i'm new to this site and v6's so any info would be great.One other thing,correct me if i misunderstand'
but the 2.8,3.1,3.4 are flat tappet cam engines and then when get into 3100
3400,3500 etc these are roller cam engines or just certain ones? Is there a cheat sheet available anywhere that would tell us as to whats what for a newbie? Thanks again

go check out www.milzymotorsports.com and/or contact mike miller, he is the owner. he has 3500 top swap kits available on his site. you can buy the 3400 ported and polished UIM, LIM, and gaskets with the Manifold ported to accept the larger throttle body (65mm i think) for like $300 there too. there is, of course a core charge of like $150 or something like that.

or wot-tech since I an 60V6 specific:P

The iron head 3.4 camaro uses SFI on the flat tappet cam so its difficult to get a performance cam. A regrind is the only solution I am aware of other than a custom billet cam. The 3500 top end is the best way to go and if you keep your stock pistons, you will have over 11:1 compression (which is fine with tuning and a cam meant for the compression). Otherwise 3400 pistons drop right in for a little over 9:1 compression.

Stay away from Milzy.. unless you want to go slow, but that's a debate for another day.

I'd slap in a H260-2 or a H272-2 cam from Crane, the 3500 top end and a set of headers. Even stock for stock the 3500 heads will gain you tons of power. Your car is OBD1.5 so tuning isn't going to be easy. Your best bet is to either piggyback a OBD1 system and tune it with an eprom emulator or do a OBD2 conversion and get setup with one of those fancy tuners.

OBD1 is fairly simple to tune, lots of good code to start with and is very well supported. Lots of us have wildly built V6's running reliably on it.

262 cam with that high compression is difficult to tune. Go with a 272 cam at the least. You will need a way to tune if you do the high compression since your ECM doesn't have any options. Headers for the iron heads will work with a little modification...

You will need to do something about the coolant sensor. Easiest is to re-tap the 3500 head to accept one from your iron head.

3500 upper manifold will not fit, you need to use one from a 3100 or 3400.

Throttle cable from a 1996 GMC Vortech-powered truck has one long enough and fits.

Coolant hoses need re-routing, the timing cover will need to be notched, and the accy brackets need re-drilling.

I've covered most of this in my threads in the past and am probably forgetting something....
