These came off the 1989 T.P.I 350 that I put in my Monte SS. Emission tubes are still there. In great shape. $300 o.b.o. Locally only please. Don't trust shipping crap. These parts are all off a southern car from Florida. Also have both power mirrors for 89 Iroc just need paint $150 o.b.o. Have 1989 Iroc steering box $150 o.b.o Drive shaft from same car (not bent or anything) $150o.b.o Email me if interested. Remember or best offer! This stuff has to go!! I need the storage space. If you think I am way off on a price,prove it and I'll see what I can do...Don't be afraid to ask. I don't offend easily. kwittmaier@cogeco.ca

I meant to put this post in the classified section...Sorry Paul. Posted new topic by accident.

Never heard of high flow manifolds.... anyone have information on these high flow manifolds?

Slade1

Hmmm GM and high flow are an oxymoron.... lol

nblanchard

Thats my opinion Slade, but I would like to find out about these... they may be an option for me to get some more flow.

92zeddar

from like 89 to 92 they say that the manifolds are better flowing from the previous years... like I said that is what they "SAY" the dyno might "SAY" differently.. hahaha

trigger GTA

nope. iwould have to say no. i got an 89. nate and i have the same hp and track time. his car is an 88

i too have never heard of stock high flow

IROCKER

My guess is they are off of a TPI Vette...they, by design, have better flowing heads. I have heard of them, just never seen them or knew which year.

hey IROCKER the Vette manifolds are wayyyyyyy different than ours check 'em out sometime.

YES the log type manifolds came in 2 inch and 2 1/2 inch.

The carb'd non HO got the 2 inch and the EFI's got the 2 1/2 inch manifolds. This according to what I have learned/heard/seen.

Trivia -- supposedly it had something to do with those cursed air tubes (4 per manifold) to make these work the log had to be larger inside diameter than previous.

I guess I have everyone thinking now Aye? The people at GM themselves had told me that the 89 and 90 Irocs, had GM highest flowing manifold in that era. Probably isn't a huge amount of difference. Again I was told only the two IROC's got these... The car they came off of, also was a southern car from FLorida. Hey just going by what I've been told by a lot of others! My 85 Monte SS's original manifolds port is smaller than these Iroc ones. The Monte SS did have the H.O. engines, but like said it was carburated. I will sell for less. Just wasn't to sure exact cost. Don't hurt me though. LOL

Flow more or not...For that kind of $$ you can just get your stock manifolds ported...

When I got my engine done, the guy told me the manifold design was really poor. This is in 87 at least.
He said the exhaust has to rise into the manifold as it exits the head, before it is forced back down and out.
Beats me !!!!

S@&t, like I said wasn't sure on a price? Come give me a $100 for them for all I care... I figured someone would actually give a price that they are worth. Nobody did though. I was told that these are a half inch bigger than carburated stock ones. So for a person with a stock carbed car this would help them some and keep it emissions legal all together. I'm no camaro specialist or anything just heard a lot of others, that know a lot more then I about these cars. Is no one interested in the other parts? make me a offer. I don't care what just make one. DOn't be stupid and offer $10 or something that will waste my time. I just need the space. Best offer can take it away!
