hello, seller and I came to agreed upon price on 69 Malibu 350 original engine . given it not been rebuilt, can I still get buy just using unleaded gas? the car is basically stock except for HEI, headers, and 600 Edelbrock carb. car is an auto. thanks
i have a 79 t/a 403 with the flat tappets and i been running 87 for a couple years so far. |

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.
