I'm trying to locate the post that had corvette ramhorn part #'s in it. Does anyone have the link or the coenciding 350cid left and right manifold #'s
It would be a big help. Thanks

I don't know the part #'s, you could call your local GM dealer. Only thing I have is this: http://cgi.ebay.com/ebaymotors/ws/eB...tem=7949431772

go to www.gmpartsdirect.com look up 63 corvette manifolds for a 327. They have a 2.5" collector vice a 2" stock on our trucks, I have had mine for almost 3 years now. They have the cast in brackets for a compressor and generator. I cut mine off.

3797901 left side I didn't see the right side. but never fear you can buy two lefts and use one on the right. $108 each. I paid $86 each 3 years ago.

I checked with Carr Chev HP Dept...all three of the GM Vette 2.5" manifolds have been discontinured...just like that they are GONE!
Damn GM does that a lot. They were running discount specials in all the major car pubs for years and then they discontinure them.

I noticed that the '68 327 Turbo-Fire 250, 275 and 325 hp engines had exhaust manifolds similar to the Z-28. If these high horsepower 327's had this exhaust and the Z-28 had this exhaust, it must flow much better than the stock Ram Horns. I have a set on my 305 and was looking at them and just thinking why don't I put them on my 283 or 327 for better performance. I am wondering it there is a difference in the internal diameter of those as well. Any experts out there?

the ones I found were under restoration on GMpartsdirect website. mine were cast in 2001. they are listed for 62 and 63 vettes
