Which exhaust manifold 970S?

Post by KA2S4 »

I'm needing some advice/opinions on which one to use,

The motor is +60 with a 544 and a pretty std S head, std carbs with trumpets, on a sccr box and a 4.1 diff.

I have a Cooper freeflow an LCB and one i've not seen before, which is 3 into 1 but they join up very late.

The first one fits with no mods, the LCB fouls on the spring bridge and the orgasmatron fouls on that and the heat shields.
I don't mind spacing the carbs a bit but just wondering which one would be best for my motor?

James.

I'd go for the freeflow, my engine runs 1293,544 cam,twin inch halfs and the freefow
Gives better low end torque which is what I wanted for a regularity rally car, plus there's less joints to leak.
LCB would also be ok as long as it's not to big a bore size but the 3 into 1 is for the racers

;)James,
I will opt the LCB for your 544 cam, note the lcb STD bore is the propular ST goodies of those day!but bear in mind the UJ if not using Hardy spicer one will foul your down pipe (the rubber joint type).
I had started my CCC assembly slowly! :oops:
