I was thinking about the 2117 1/34 hooker super comp headers.

Do they fit with air conditioning?

[Straight-line-69]

You' be ok with 1-3/4" tubes but most would recommend 1-5/8" headers for a 350 that never sees the dark side of 6000 RPM.

[Everett#2390]

Hooker 2130 would be a better choice, 1.62" OD X 30" long.

What is the size of your exhaust ports, doesn't make sense to go much bigger than that or the velocity will suffer in more ways than one.

[fast69camaross]

ok.What size exhaust would you recommend?

[zdld17]

Nothing larger than 2.5" pipes . Its an over kill going larger.

[fast69camaross]

My engine builder said keep the 1 3/4 headers and go 2 1/2 on the exhaust.Will these fit with the air conditioning?
