3.1 v6 60... parts selection

[bszopi]

I think it was a custom piece. I looked at the old thread where I originally saw it and tried going to the ebay item #, but it said it was invalid. Then I did a search on ebay, and nothing came up.

Here is what you should do...

who made the intake and how do i find it???

[ForcedFirebird]

RWD headers fit if you open the mounting holes a little (Camaro/Firebird, S10 etc). Not sure of the mounting configuration in the rail, but this may be a cheap/easy for you and give you a few choices.

S&S headers makes a set for the GA that would fit the alum head engines. For the iron heads, Edelbrock used to make some, although I'm not sure the current availability of them. You can also do custom. Contact betterthanyou on the site for a set of flanges.

Might also want to look on ebay, as I know a few months ago, there was a custom intake to allow a carb on aluminum heads. Not sure if it ever sold or not...

and where are you guys finding headers?

well cool but if the 3.5 heads fit on a 3.4 wont they fit on all 3.4's? and cool makes sense on the cast headed piston.. i was trying to simply do a quick find on summit and no go.. ill reffrence them on a book.. with the heads i still have the problem of intakes till someone makes a intake for a carb and distributor for alum. heads im ******... but ari said they have plans to do so... but there rumor is there gonna make it so it'll only fit there heads.. dave thanks for the help

are the parts interchangeable from the 3.5? and superdave the compression height of any 2.8 piston isnt gonna work with the larger stroke of the 3.1

correct, the compression height of the 2.8 and 3.1 are different.. so if you are using a 3100 V6 with the 3.31" stroke crank you'll need to use 3.1 pistons form an iron headded engine.

the 3500 V6 parts will only fit on either a 3400 V6 (generation 3) and a 3.4 V6 (93-95 Camaro) due to the combustion chamber size.

I went with the whole 3500, it's 201 HP stock.. with a cam, headers and port work mine is pushing around 320 HP on regular pump gas.

2004 to 2005

3500s are newer, 2005+ I think. Not hard to find. $500 for a 30-40k mile engine from the salvage yards around here. Search for a 2005 Pontiac G6.

super dave thanks... and ive never even heard of the 3.5 i take it there hard to find... do the parts interchange? and the reason im going to cast heads is because of the intakes avialble...

few more graphs in that thread..

Ben has flow sheets posted somewhere for 3100 and 3400 heads.

[Canyonero]

Do you have flow info for the 3rd Gen heads?

[Superdave]

I won't comment on ARI but for the original engine you posted about, to use the iron heads you'll want to simply get the pistons out of a 3.1 Camaro, or order a set for one. they'll be nearly flattops and get your compression back up to a useable range.

Also, remember to use headgaskets for a 2.8/3.1 Camaro/S10 because they are thinner than the FWD ones and get you back to stock 3.1 compression.


it's not the compression loss that costs power, the iron heads flow terrible. Check out this graph showing the difference between 3.4 iron heads (the same as 2.8 and 3.1 irons) and the generation 3 3500V6 heads (the best out there for these engines).



Even ported the iron heads can't touch the FWD heads.

Thanks... i also wanna say im getting alot of help from a company called ARI... @ engine-parts.com
the 2.8/3.1 i found out is being used back east in mini sprints for dirt track racing
