What about a 4.6L?

[oldbloke]

My mechanic has a rebuilt 4.6 sittiing. Have heard this has been used in a P6 before. My '70 NADA is getting tired...! Would love to find acceptable 4-5 speed, but LHD pedal box for these are VERY rare. Therefore, my question: can a BW T65 be mated to this engine without too much difficulty as I have access to a rebuilt one of these as well? Also need opinion of this engine?

4.6 fine... i'd expect it to chew a bw65 to bits given the extra power and the reputation these boxes have of being marginal for the 3.5 v8....

now if you can source the right sort of zf4hp22 box you may have more luck...

The BW65 copes with the RV8 in 3.5 form without too many problems, and uprated to BW66 spec they went behind the XJ6 with 245bhp (approx) and held up there as well, but a RV8 4.6 would probably kill that as well if the loud pedal was brought into play too often.

D and D ( in the States ) sell the adaptor bell housing you will need for a manual trans. conversion;

One of these would be rather interesting if D&D ( or someone else) could adapt a bellhousing to fit

I believe Ron runs the BW 65 behind his 4.6...AFAIK he has beefed up the internals somewhat by using BW 65 Ford bits.
Says it is perfectly acceptable as long as you don't mash it from a standing start or partake in throttle lunacy.

It's a 35 IIRC, but I'm sure he'll be along shortly to confirm.

My Rover's transmission was originally a BW35, which has been upgraded to M51 standard. In this format the tx has worked perfectly for almost 90,000 Miles (145,000km), all behind the 4.6 litre engine.

As Brenten said, I don't slam the throttle down or use kickdown, essentially because with the bigger engine, the torque delivery is so much greater that there is no need to drive this way.
