TR6 tr5 tr6 engine specs

[willeng]

Looks like a good Forum Guys!

Could somebody help me with the centre/centre length of the std TR5, TR6 conrods.

I am also after the conrod journal width measurement of the std crankshaft & the maximum oversize bore diameter leaving enough cylinder wall thickness for a high performance engine.

Thanks

Hello and welcome to the forum. Try this link ( https://www.trparts.com/tuningtips/index.html ) and download the "Tuning Standard Triumphs over 1300cc" pdf book. Engine overhauling and specs start on page 11.

Good luck,

Brosky,

Thanks for that, not much there for what i was after unfortunately.

Hello Willeng,

not that much in the workshop manual either, crankpin width is given as 0.9066" - 0.9085" and maximum overbore is +0.020", but I know that an overbore to 2.7 litre is practical.
