Phil has never updated the web site. There is no 4.6 short complete. TRS do reco v8's to order. I opted to keep the 4.6 heads. I read somewhere that the RR 4.6 heads had a slightly different port design. The extra torque is very noticeable and so is power especially if it's a high comp - stock high comp was 9.35:1. Generally Aust RR was low comp in the 4.6. High Comp is also better for LPG. I have a BRC Impco.
Cheers
yea but the 4.6 piston crown CC is 22.29,,whereas the 4L is 13.23,,
does it make a seat of the pants difference??
who knows:p,, but with compression, smaller is better:cool:
Late Edit, it would seem this is the difference between high and low compression Thor engines
Have I got this right?
The distance from the (edge?) piston crown to the center of its crank bearing?
Can anyone tell me the two measurements?
4L Vs 4.6
Thanks
I didn't know that it was smaller...so what does that take the comp too?
Cheers
who knows,,
I asked that question in the Tech forum and got a lot of dead air--
I've also just asked if anyone knows the different lengths between the 4L rods and pistons and the 4.6,, I think its around 4mm,,
see here part 3--;)
Buick 215 Rover 3.5 Land Rover 4.0 and 4.6 differences
Due to the typical response I get from posts in the Tech Forum, I've moved it here hoping for at least some info.:angel:
Thats hard to find, mostly only concerned with stroke and piston crown clearence. Given that the stroke on the 4 is 71.1mm and the 4.6 is 82mm and both use the same crank, the best would be to have an actual set and check. Thats about the best I can think of or find at the moment.
