Thank you ALL for the replys, has turned into a good, thought provoking thread. Again, car will be a cruiser, and see time at 1/4 mile strip. Must drive to and hopefully from. Originally was keeping 3.31 stroke, drag cam and 850/950 hp carb. I now want and am using e.f.i, therefore the 106-108 l.s.a cams are out. (need 9-10" of vacuum) still will be big lift 240ish duration i hope. Will be custom. The heads have long valves etc: So, as stated, am going to add stroke. The 4" stuff looks easy and reasonable. Not seeing a lot of 3.79" stuff, or matching 6.250" rods with 4.00" stroke, 4.070" bore pistons. I posted on 318 cams thread. I will be using a 8 3/4, 3.91 suregrip i bought. Again, thanks to everybody!!
