So 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.

I 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.

Congrats Ben!! Crap fuel sucks, but that's about all we can get anymore.
