Thread: Maximum bore...

As of right now my mind is set on keeping it all motor. I am just waiting on a few phone calls back so I can start making some moves. Plan is to build a basic 90mm VE motor. Looking to make in the 240-250whp range. Actually buying a real 4-1 header for it and ditching the ssac 2.5''. If I can harass him enough, i'll have J up in CT make up a manifold for me. Either that or going to have to get fancy with an Xcessive plenum and longer runners.

Yeah same here in minnesota with b-series. Our ve's are hurtin them until this past summer where finally some are getting more serious probably cause they're tired of gettin beat by se-r's.

^^^ Funny

Max bore size on Darton Sleeves is 92mm but we suggest only going 91mm. Our gasket measures out to 91mm. Stock bore can probably only going to 87 then it will crank at the coolant jacket for sure.

Best combo will be 91mm/92mm. That will be 2.39L, some high comp pistons, light A-beam rods and some Kelford custom ground cams and it will make some serious power.

that 2.3 b4 the crank u sell?

Huh?

going 90mm bore will defiantly make some power. You will be able to deshoud the valves properly. With headwork, intake manifold, headers, high comp and cams you will see some serious power.

Those cranks look nice too. Do you have pistons set up with standard rod length? or shortened rods?

92mm wit net how many litres on stock crank? reason being, i was on the phone w/sum1 talking bout doing a 92mm bore along with crank.. what would u say that the highest displacement our block can achieve? 2.5 give or take?

he was just saying he reccomends 91 bore and 92 stroke for 2.39 liters

You suggest that because of the sleeves or headgasket? Im just wondering how the headgasket would work with a 92mm bore.
