Hey all, a friend of mine who lives in the Philippines has a 75 vette...its a beautiful car and its both show and go, nice car. Anyway he has a question to which I can't help, maybe someone here can? Thanks in advance.

"now a question concerning my vette: I want to buy the march serpentine system, but it seems I cant get a straight answer from them. will this bloody reverse water pump fit on a 75? what about the PS pump, on one website the wrote it’s a 5 groove and on the other it’s a 6 groove pulley. so what is it?
I want to buy the whole thing beside the P/S pump so who knows something first hand about it? I'm a bit slow to order cause its really expensive and I want it to fit properly the first time. just installed my VBP monospring front end, with upper and lower A-arms and man I'm finally happy how the car handles. put rack and pinion, smaller steering wheel, bilstein shocks, new bushing everywhere and the car handled like **** at 90 miles. way too much power steering, over response etc. but the VBP stuff did the trick. finally I can drive with one hand and still can talk on my handy with the other. will order now the rear end too ( yeah I might be crazy, but I really love this car, that is one reason for the high price, I'm not really into selling it ). so if you could help me out a bit how to go about the march system I would appreciate very much."

 

I wish I could help, but I wanted to let you know you're not alone in NOT getting good tech support from March. They've never even responded to questions I had about certain BB components, and I think I'm just going to convert to a cog belt system similar to 84rzv500r's.


Here's a bump, anyway. TTT

 

Thanks anyway,

 

Reverse flow water pumps were installed on 1984 and later GenI engine Corvettes (simular motor to the 1975 Vette.) The lower radiator hose should fit correctly with the new pump. Don't know about the large diameter of the crankshaft drive pulley and front crossmember clearance, everything else seems to be OK.
