2.7s cis upgrade - suggestions

[advtracing]

I have a 1976s R-gruppe car (990kgs) , i ripped the cis off last year and went for 40 ida's . the car has been running well but the lower end was warn and is showing issues and oil burn.
Time to rebuild , so i need a few solid suggestions for upgrade spec's.

thinking 2.7 case , 930 oil pump , std rods , je pistons and cylinders bumping to 9.5.1, cams ? , plus ..

oh come on , no way . lets keep period . must use the 2.7 case

Case savers and Supertec head studs to make it live. A modern EFI system (Motec, etc.) using PMO throttle bodies would also be nice. Coil on plug technology?

Speed costs money, how fast do you want to go?

With what you've outlined, the heads are going to be the flow restriction. You're looking at port 'n polish. Plus, depending on what octane you've got available, @9.5:1 you're at the outer limit for single plugs. You're heading into some serious money here. Run the numbers on a 3.2 swap, and consider putting the 2.7 in storage for a fussy future buyer.

If you want a great old-school hot rod motor.....A 2.7S with weber 40's, 9.5:1 JE pistons, E-cams (or equiv), SSIs and a sport muffler.............is a great 911 single-plug, hot rod, street motor. You will like it. I am building one as we speak.

regards,
Al

PS: take that same recipe, but use EFI/ITBs..........better yet.
