the 1987 intake has a small port in it for some BB applications. I picked up a solid .15 by porting mine on a stroker that had ported 906 heads.

Well, I have a question about tunnel rams. I remember reading a while back, going to show my age, but the article was about taking a tunnel ram for a B block and making spacers out of pylwood so it could be used on a RB block. Could you do that and open the ports up to M/W size? If you did that would the runners in the manifold be large enough to support the M/W ports in EZ-1 heads? I know it would work, but would it work as well as the Indy tunnel ram? If not what could you expect to loose with this set up? I know it is only a guess, but just wondering.

I ran a pair of 750's, converted them to 4-corner idle circuits, and Dominator style secondary throttle blade adjusters. Used the Enderly linkage.

Dodgeguy, just have aluminum welded on the tops of the runners and port to Max-Wedge size, guys have been doing that for ages.

Shoebox I helped build almost that exact combo 440 .030 2295f stock crank and rods w arp rod bolts. 590-312 mp cam home ported edelbrocks M1 tunnelram w 2 660's 727 w J converter 4:30 gears in street valiant ran 10.30's at 130 trust me nothing fancy but took a beating. the owner is a member here maybe he'll chime in

Awesome! I always wanted the 590 but I need to keep the rpm's in
Check. This 256 108 cam should drive a lil better I'd be thrilled
With a 10.xx @123 with my car!

Its a simple combo that is very effective, but I still think it requires a little rpm to get it to work good. TR's by nature tend to like a little rpm. The car responded well when I moved the shifts points to 6600.

The 4200 converter hurt my car more than anything as it was always a struggle to get the car to 60ft in the low 1.50's. When I called PTC, he suggested something in the mid to high 5000 range to make the combo work better. So at the 4800 you will be a little better off than I was. Overall, I think you will like the combo and it will do what you want.
