Inliners International Forums General Discussion Engines Cast 307 Pistons in 250 L6 swap

I ran a similar set-up.

I used forged 307 TRW pistons,(currently still in car) I have a positve deck of .002- .004 my 194 head was milled a lot, cannot remember the current cc's but I had 12.0:1compression camshaft ,,,, (going from memory) .560 lift 238 intake 248 ex. degrees duration @ .050 & all cylinders cranking compression was 220-230 PSI range.

I ran 3, 48 MM DCOE sidedraft Webers & it was by far the fastest & most torque my 250 engine ever made.
Really put a smile on my face & surprized many guys on the street.

This was my daily driver & I enjoyed this combo the best for overall driving experience. When I used a Paxton supercharger blowing through the same 48's, it was faster, but not from the start.
