I put together that current engine way back in 1986 or 7 . As a result I am a bit foggy on the details.....however I have it all written down......somewhere
I built it because have always loved the looks of dual quad tunnel rams and could not afford my first choice, a polished 6-71 blower! Also I was told you could not run a tunnel ram on the street....so of course i had to do it
I do know that it is a Edlebrock intake. I liked it better than the Weiand intake which had larger runners. The Edlebrock looked like it would work better at lower rpms than the Weiand.
I started off with two 390 cfm Holleys, put powered seemed to drop off on the top end. I then put on 465 Holleys , they worked better. I don't remember what jets or PVs are in it though .... most likely i have it written down. If nothing else I will know when i open them back up . They definitely need a rebuild . The whole car has sat idle since 1990!!!!
They are vac secondary carbs with a vacuum equalizer tube running between them. crud i know i changed the springs in there too.... I hope i wrote that down as well!
The cam is either a Crane or TRW , I have had many cams in this block , not sure which one I ended up with but i will look it up this week. I have a complete folder on all the parts for the car ....again, somewhere.....
It is a hydraulic cam , makes power from 2500 to 5500 or so.
I set up the whole drivetrain to maximize power within this range , 2500 to 5500 ... the cam and intake start making power about there and the torque converter locks up at about 2500 ....
The pistons are flat top , works out to about 10:1 CR with the iron camel hump heads, 2.02 intake valves (remember it was the mid-80's LOL) .
All in all it worked great. I drove the heck out of it . And it ran low 12's in the 1/4 with 8.5 " wide street tire using a 7.5 rear end ....3:73 gears. Now that I have put the narrowed Ford 9" in it with a 29" tall tire (vs a 26" tire) I will probably use a 4:56 gear or at least a 4:10.
