It's been awhile since my last post. I took a long weekend and spent the 3 1/2 days rebuilding the engine in my '70 GTO. It's a project thats been in the works since this past April, acquiring parts, figuring out what to do, etc. I finally teamed up with Bruce Fulper of Rock & Roll Engineering; he's been building Pontiac engines with amazing results for quite awhile. Bruce seems to be a pretty cool cat, always eager to lend some advice.
Anyway, after becoming tired of mixing fuel and plotting trips, airport to airport looking for 110+ octane to keep the goat happy, I caved. Bruce spec'd out a custom cam and reworked a set of cast iron heads for me to lower the compression in the ole 400. I know, I know – but this is right up Bruce's alley. Added to the mix is an Offy 2X4 intake with a pair of Edelbrock 750's, a MSD 6AL box and their Ready-to-Run distributor – I'm using a progressive linkage on the dual carb setup.
So after three very long days, she finally roared to life last night and sounded great. I still have some tweaking to do, timing, carb adjustments, figuring out the throttle linkage, etc, but it's been a blast. Hopefully I'll wrap-up this stuff tonight and take it out for a seat-of-the-pants run. Stay tuned.
