It will run fine on unleaded. Use lead additive if your going to seriously wail on it tho. Protect the valve seats.

question. I basically have determined that my 69 has the 255 hp version of the 350 engine. it is match numbers, and previous owner said it had a 2 bbl carb originally.

question. what would be a good guess on horsepower now with the long tube headers, 600 carb, alum intake, and open air cleaner? thanks

Remember those are gross ratings, not SAE net. Net vs. Gross is about a 25-30 percent difference.

oh ok. I was just wondering approx. what it would be with the add ons. the seller really didn't know.
I didn't realize how heavy a intake manifold was! no wonder peeps put on aluminum intakes. wow, I about pulled my back trying to lift it. the air conditioning box isn't that light either. and the air cond. compresser is heavy. now I see why peeps don't keep all these on the car for all the weight.

Pick up a set of big block heads, that'll get your attention.
