This is my story and I'm sticking to it......

I bought a 1969 GTO that was advertised on this board a few months ago. It was a divorce situation and the woman ended up with a car (partially disassembled and in mid-restoration) that did not run but had a freshly rebuilt engine sitting between the rails (so she said). The only thing she knew about it was that the guy that built the motor used to race Pontiacs.

I'm now trying to figure out what the engine builder had in mind when he built the car. Here's what I found. It's a 1975 WT block with 1971 code 96 heads (86cc I think). It has an Edelbrock torker intake without a carburetor. The cam measures about 218 degrees intake duration and 230 exhaust duration (both measured @ 0.050"). The lift is .447" intake and .468" exhaust. Lobe separation measures to be about 130 degrees (can that be right?). There is no identification on the front of the cam. The cam gear has the numbers S305 on the cast surface and the crank gear has the numbers S371 stamped into it. The timing marks point at each other at TDC rather than both pointing up as they should be since it's a post 1968 motor.

I'm going to assume the motor has been bored since it looks like it has new (never fired on) pistons when looking through the spark plug hole. The engine builder also installed new "4 tube" headers.

I'm certainly not a Pontiac performance expert, however, considering all of this stuff together make me think this motor was built for more of a "drag strip" application than a street application. Can anybody confirm my suspicions? I want this car to be a daily driver, not a drag racer. What can I do to build it for short daily commutes without investing a whole lot of money.

Thanks in advance for any help.
