efi take with carb welded on

seriously dumb question im sorry


I have been searching and I know its been covered. carbing an LT1 motor.
for ratrod s10.


my question is. instead of buying old used sbc mani and drilling it.
could I use the stock EFI intake mani and weld closed the TB hole. and drill a large hole on top and weld an adapter and bolt on carb?..


or wouldn't work because no actual runners? new to old carb stuff.....sorry
im for more work than spending. even it ifs ridiculous(within my capability)
just want this motor I got basiclay free to run and make this s10 move some how

Re: efi take with carb welded on

Sell the EFI stuff (better yet, sell the entire engine).

Buy a used carb stuff (and a ratty SBC).

Pennies (and self-respect) saved.

Re: efi take with carb welded on

Why bother welding up the hole? Just use duct tape.

The carb on top of the TPI plenum definitely looks rat rod.

The knowledge we have of how runners and plenums and stuff works is the reason you're getting the responses you are getting. I just hate to see a good LT1 go to waste.

Don't rat rods HAVE to have a big block? Pretty sure there's a rule out there that they do.

In fact, we do.

Which is why none of us here would EVER do ... THAT ... to a perfectly good Holley.

That's the sum total of the worst of all worlds, right there (aside from the alternate-ethnicity-of-your-choice engineering): the wet flow of a carb, the "tuned" effect of the TPI runners. Doesn't get much worse than that.
