I was wondering if you guys could help out a Pontiac newbie and his son. Short historyÖ
My son (16) has wanted a 69 GTO for a while, kind of like I wanted a 68 Charger when I was 14. We finally found one, bought with his own money. Itís a standard 69, came from factory with a WT 350 HP 4 speed M20. Unfortunately, the original motor and trans are no longer in the car. Whatís in its place is a W72 from a í79 T/A with 6X-4 (whopping 220 HP stock, 8:1 CR stock) heads along with a Saginaw 4-speed. We have no idea if the motor has had any work done to it, though it does run pretty well from what I can tell. It has an Edelbrock Performer RPM intake manifold with a 750 cfm Edelbrock carb, and Hooker headers.
Now we need to sort out all sorts of stuff, starting with getting it street legal.
First thing we needed to do was to replace the engine harness, as it was hacked and literally held together with tape, a fire waiting to happen. We ordered a standard internal regulator harness from Performance Years, but Iím thinking that may be a problem, since the battery and starter wires run down the left side of the engine to the starter, way too close to the headers for my comfort level.
Question 1 - Would the Internal Regulator/RA harness work better, since it seems to run from the front of the engine to the starter (I think)? Weíre hoping it will clear the headers and not melt any wires.
Question 2 - Would I be able to use 69 RA III exhaust manifolds with the 6X-4 heads? According to Wallace Racing, it should work. Iím thinking 9797072 and 9791637, but Iím sure not certain. Iím sure weíll lose some ponies switching to manifolds, but I can live with it. Not so sure about my son, though.
Question 3 Ė wantís the best Pontiac repair manual out there?
Anybody got a great deal on a Muncie?
BTW, yeah, I did get my Charger. Not till I was 21 or so, but I did get it. God I loved that car. Now itís the kidís turn.
Weíll probably be asking lots more questions in the coming months, and hopefully we keep the dumb questions to a minimum.
Thanks in advance for any assistance.
