I've E-mailed Ta performance a couple of times during the last few months wanting the prices of their Offenhauser dual quad and tri poawer manifolds but they never e-mail me back. Anybody got the prices on these??
Page from TA catalog Here you go Mike, Just call them, 480-922-6807 There is a side note stating that there are hood clearance issues with most 50's thru mid 60's Buicks. They recommend the low rise version manifolds be used with drop base air cleaners. In some cases, it may be necessary to cut the studs that secure the center hood moulding.
I see these listed TA 5882 7 329.00 Offenhauser Dual Quad Hi-Rise Intake 400-430-455 TA 5885 7 346.00 Offenhauser Dual Quad Hi-Rise Intake, Quadrajet 400-430-455 Also I have their catalog here if you would like me to look and see if anything else is listed..Otherwise you may have to call to get any updates etc.. Take care
