Suitable pistons?
Posted: Wed Dec 22, 2004 11:55 pm
Hello people,
First time on the board, there is some interesting stuff here, a couple of questions you lot may be able to help with.
I’m thinking of a (cheap) stroker using a 3.5 with P76 crank, I know about the main bearing size issue and can handle that. Using the standard rover rods, has any one a suggestions on suitable pistons? (Ford 170 pistons look interesting but I haven’t enough information to be sure). Failing that can anyone give me an idea on the required compression height or the deck height of the 3.5 motor? (or should I be going the other way and replacing rods?)
The donor 4.4 was in my RR when I brought it, unfortunately it had digested a screw from the carbie (yes it was cheap), It was a recent rebuild so I tried replacing the damaged piston but unfortunately the damage included a moving liner. Has any one had success in pinning the liner after it has started to knock?
One more, am I right in my conclusion that a mid 80's 350 Buick v8 Hei distributor can be made to fit without major mods? (Except grinding the manifold)(its a standard 1983 high compression motor with an early pre-emission Cam) if so why have people gone to the trouble to convert the V6 distributor?
Any advice on what to look for if I splash out on eBay for one? (Mine seems to take a lot of advance to get it t run on LPG, I suspect I need more sparks!)
Thanks
Fred
