manchestersharkcthulhuSo I made the carb swap to the street avenger.
I also had a problem with the vac advance on the msd distributor advancing too much. i would up making a limited out of sheet metal to prevent it from adding 18 degrees of advance. I am limiting it to 10 degrees.
Also, I bit the bullet and swapped the cam. The comp magnum 270H was getting me 10" of vacuum and that just isn't streetable. I had the timing way advanced to get it to run and then it was running hot and boiling the gas out of the carb.
I changed it to a Comp Xtreme energy 264HR. Same lift, very close on duration but much smaller valve overlap because the lobes are less round with the HR vs H. I am getting 16.5" of vac and the world is a better place now.
when i started building this car i wanted to drag race... now i am 16 yr older and have no interest. i just want to street drive it.
cthulhuI can get ethanal free 93 at one local station (lots of places have it as 91) but I have had a number of times when I look down at the gas gauge and realize I am about to be pushing it and I find the nearest station I can and put in whatever passes for premium.
Adams' AppleCongrats Ben!! Crap fuel sucks, but that's about all we can get anymore.

yes indeed. Definitely sucks.
on a good note my 22 yr old wants me to resurrect the 81 barn find for her so i may be passing the torch as well
Bluesting 70Nice! I agree with the wheels. I’m in the process of putting 18” on mine. What is the cut out of your heat shields? Where did you buy the roll bars? I can only find one place that sells them.

I dont recall on the roll bars because i bought them ar the start of the project in 2004/5. But i have the box so ill get the name when i go out to my shop next.
also on wheels im thinking either 19-20. Enough to make it past the ebracket in rear and tie rod ends at front.
I am running 255/60/15 (27.4” diameter) so even at 20” id still have 3.5” of sidewall
might have good use for the very new tires... the 81 barn find
That will give me an excuse to buy my new wheels and tires
