New block build
Posted: Sun Jul 28, 2019 11:02 am
Hello all, i've decided to re-block my tc and have aquired a NOS 1500 block. I'll be using most of the parts from my tc. The tc block was touch and go to repair without removing the std liners (on +40) and fitting new, so we honed and hoped for the best, but i fancy building something else and am not a stickler for originality although i will hang onto the
L block.
Obviously it will require a rebore to get to the standard lotus size, but i was wondering about crankshaft options. My current crank is -20 mains and big ends and 90k miles old, plus is worn at the rear main seal which i appreciate i could repair with a sleeve. I could transfer all of the bearings, so a cheap option.
Second option which i'm trying to explore is using a 711 crank. I understand its longer stroke so i'll need shorter pistons from somewhere, plus some grinding of the block for clearance, will it work with the 1500 block or do I have to go 1558?
