Thread: Head swap for 250 I

Tweet

My ultimate goal is a bullit proof engine. I spend a lot of time way out in the desert away from help.

I have a stock 1979 chevy blazer with a 250 intergrated head. Will a non-intergrated head bolt on with out a major refab?

My plan is to swap heads and then go with a Clifford manifold with TBI. Yes I plan on all the other changes like exaust, air filter ECT.

Last question, for now, 250 I6 or 292 I6.

In your opinion, will a TBI setup be more bulletproof than a carb setup? Do you get the vehicle sideways/tilted so that a carb wouldn't work as well because of the fuel bowl/fuel slosh?

Yes I have goten into a steep or off camber enough terrain that I lost fuel. This has been rare.

I am not fully sold on carb or TBI at this time.

I have worked on my own truck for years, but only repair or replacment of stock items with like items. So I have much to research as this project comes together.

Thank you for all of your help so far.

The heads are interchangeable. A 292 would make lots more torque. A carb can be fixed out in the boonies, EFI can strand you.

So 292 w/carb, sounds good.

Any other information or ideas? Oil cooler, electric fan ECT.

Thanks again
