Identifying Intake Manifolds
 
I purchased a set of 40 IDA 3C/3C1 Webers back in 2018 for a 914-6 2.4 project. Can anyone tell ne about the intakes? The only markings are F.R.P. cast into them.
Top side has 40mm ports. Bottom side are 35mm.
thanks

Sorry I posted twice. I was trying to add a couple photos.

Just go back and delete the other two threads.

I have not had any success with deleting the duplicate posts. I've attached a pic of the intake and carb.http://forums.pelicanparts.com/uploa...1762909786.jpg

...and the cast marking is R.E.P. - not F.R.P.

Did a quick Google search. Apparently REP may be pre PMO.

OK, thanks. I couldn't find anything when I searched.

I'm not certain about the manifolds but the velocity stacks came from TMW.
Now sold under the Borla banner.

REP is PMO. Can't recall what REP stands for though.
