I am going to do the engine last but want to be thinking about it now. My Boss 302 needs bored out . I guess it will be .40 over and the crank 10/10. I will only drive this beast once or twice a week after it's done. My plan is to keep the engine looking factory out side but more modern inside. I am open to out side options but I think the soild lifters will sound like the origanals and with roller lifters saving friction. I am pretty sure the 780 cfm carb with be stored as it it way to much carb.(?) I am thinking of a gear venders OD unit as the 3.91:1 Traction loc and Close ratio Top Loader will be good but I live 60 miles from work (Anchorage ) and don't want to fill up three times a day Thanks

I just want t make sure I understand you correctly, you plan on putting a solid roller in the car? Right?

A solid roller with a good exhuast system behind it makes more noise than a flat tappet solid cam. Plus you can hear the roller lifters "whir" inside the motor. Actually, it sounds neater than s**t !

I am not sure if that carb will be too much or not. For street driving it might be a little big, and coupled with those huge ports you arent going to have any low end torque, but once it gets wound up it will definatley like that bigger carb. So, I think I just talked in one big ole circle and didnt say a d**ned thing

Sounds like a neat car. I have a 70 Torino Cobra that I've done the same thing with. It looks stock on the outside, but has the goodies inside. If you're considering a street roller cam, the Comp Cams Extreme street roller series is nice. They run a fairly tight lash (.014-.018") so they use fairly light spring pressures and avoid some of the pitfalls that people talk about with the larger racing style roller cams. The performance for these cams in street cars is awesome because they tend to have a fairly mild idle but because of the aggressive lobes they build alot of power and torque.

Also I used to have close ratio toploader in my car. I couldn't stand that high first gear. It was like taking off in second. I switched to a wide ratio and I love it. If I understood you correctly you're considering a 5 speed tranny. I think that would work great with that boss 302. Maybe a tremec or something like that might be nice, but I don't know if they are OD trannies or not.

Kid, Mike Thanks,
I Am thinking about the port plates for low end torque Gear Vendor makes a bolt on OD unit that replaces your rear trans cone. I know that the top loader is heavy put I'll keep it for a long time. Mike I lived in Indy until 92. ever seen my Torino GT See Sig.

When I was racing my 70 with a 4v cleveland in it, and the car was seeing a lot of street use, i tried runnign port plates. I couldnt tell any difference in the way the car drove on the street with or without them. And on the track, it didnt show any difference either. The only thing I did notice was, they were prone to leak since you dont use a gasket on them (just permatex).

I now have mine hanging on the wall of the garage where they will stay.
