Intake ??

I looked at Summit and Jegs. Is anybody making a dual quad intake for the LA engine other than a tunnel ram???

I just saw a dual quad SB intake for sale on here the other day. Also try eBay

I have one, I think it's an Offy. I'm pretty sure mine has the different angle holes for the early LA heads though, thinking '65 down?
Travis..

The Offy is still available as far as I know.

Edelbrock also had one in the 60's called the D66 but it has small 318 sized ports. There's also a D64 but I believe the intake holes are angled like the early 273's.

If Edelbrock made a more modern 2x4 intake like they do for SB Chevys I would run one.

Yep, here is one of the 273 ones my buddy in Oz used on one he recently built.

(he has a couple of the intakes, early and 'standard' small block ones he has rounded up over the years )

This is mine bought brand new in 2003. Its for the 273-318 but Im gonna run it on my 360 with two 500 Edelbrocks. Offys are weird- they never made a dual plane. This intake is an open plenum with a divider wall running center- front to back. It does not really have runners. The plenum leads into the head ports via windows. I wish Edelbrock would make an air gap 2x4 like they do for chivy. Offenhauser claimed an RPM range of 3000 to 7000 on a 273 and about 2500-6500 on a 360. I actually called and spoke to someone there back in 2002.

Dulcich tested an offy 2x4 on a 383 years ago and it did not do great. I love the look and thats why I have one.

Kind of pricey but you could use one of these. http://www.indyheads.com/modman.html

The modman is an interesting concept. I think the design of interchangeability gives compromise to actual performance but neat none the less. This pic shows how my (and all Offy 2x4 intakes) are inside.
