Hey all,

I am brand new to the forum but have used the information on here many times throughout the course of my G-body build. I have a 1986 Olds 442. Bit of a back story, my grandfather bought it and drove it for awhile before my father purchased it from him. When I graduated high school it was my graduation gift from my dad. When he gave the car to me it needed a new motor because the crappy and gutless 307 had given out. I decided to find a different motor and came across a 1978 Olds 403. We did a full tear down/rebuild on it and added several aftermarket parts to boost the performance. My question is, does anyone have an estimate what I am making at this point? I have never had it dyno tested or run at the track (yet). Its a 403 block with 350 Olds heads, Edelbrock aluminum performance intake, CAI, mechanical distributor, basically the largest cam I could fit without modifying the heads, true dual catless exhaust, high pressure oil pump, and a quadrajet. Any guesses? Also, I am looking into some shorty headers (if I can get them to fit) as well as possibly getting some aluminum high-flow heads instead, just not yet.

Thanks for the input, all.
