Small Block & Big Block Chevy Specific - Reverse waterpumps

Who sells reverse electric waterpumps for sbc?

I have a Proform electric pump and i was thinking of switch the wires for reverse rotation but the fans are curved,is there a conversion kit for it?

with a elec. water pump it won't matter about the rotation. they are only reverse on efi motors because of the belt routing. the water still flows the same just in the way the impeller is turned.

I have Lt1 reverse cooling heads on my 383sbc

Unless you are running a ENTIRE LT1 setup, it doesnt matter, that is why the LT1 has the cross over in the back for the coolant because there is no way for the water to cross over.

I´m runnig a entire Lt1 setup

I have Lt1 reverse cooling heads on my 383sbc

why? aftermarket heads flow better and are cheap for gen1's.

I have a ported set of Lt1´s flowing 275/210cfm,better cooling system ect..i use what i have for now

So...you are running a LT1 set of heads and not the block..., i have no idea whay you would do that from my stand point, i understand people running GEN I heads on a LT1.

The block would have had to been modified extensively to support those heads... An Lt1 block has 4 ports at the water pump mounting surfaces... 2 per side. The top one of these ports pushes water directly to the heads via some internal block passages. The water then pours down out of the heads into the water jackets around the cylinders and back out of the block via the lower 2 ports at the water pump...

When people convert SBC heads to run on an LT1 block, they do some extensive modifications to make it work. To convert LT1 heads to work on a SBC would require even more extensive work to be done if its even possible at all.

Exactly.

I've done a lot of research and have not been able to find any positive information on using Lt1 heads on 1st gen engines. These heads are very different and just like it was said, IT WOULD REQUIRE A LOT OF EXTENSIVE WORK! I really don't think anyone would get into doing this since there are better flowing heads that will bolt right up with out major surgery. Unless you mean first gen LT1 heads. There were engines called LT1's in the earlier years.

Yea, not cost effective by a long shot.
