340 stroker cam
Don't let them talk you into changing your pistons, Just put one of the smaller cams that you wanted or a custom one.
The engine started as an iron headed max ported w2 with w5 ports with 62cc or 58cc chambers. Hence the reason for the dished pistons.
The car was meant for more strip than street but it morphed when I met the wife with 2 kids and I already was a full time single father.
A block change due to oil seepage from the backside of the block. I took the rotating assembly and stuffed it into another block. I literally fell into some indy heads that i could not pass up during reassembly.
Now i have 3 kids plus the new baby and apparently another in the oven. So 5 kids. All the kids love the car, even the mustang loving 16 yr old boy. Hence the reason for mainly street now.
With the family dairy farm, working a 40 hr full time job and keeping the garden up to support the chaos leaves no time for track days.
Now I found the paper work for the indy heads and i had the wrong camshaft.
Camshaft is lunati 40200734
