Camshaft Selection Information

The 6k to 6.2k came from looking at the advertised operating range of the XE274 and AirGap intake. I figure the Engineers probably were a little conservative on the operating rpm ranges for the cam, intake, valve springs and the new heads.

Will try to look for the best shift points based on where peak hp range of the setup just before the hp curve starts to fall over. Also wanted to leave a little buffer in case missed a gear. Had an incident running a SBC 350 in 73 Nova where I had a crapy shifter and missed 3rd gear. Had piston to valve contact. Was fortunate to have only bent an exhaust valve in that case. Had forged TRW pistons in it and only put a light scratch on the piston but it ran like crap limping it home. Good friend had a MR. Gasket Pro shifter he wasn't using, so I put it in the car and never looked back. Could shift it without letting off accelerator. Just watch for the shift light but I shifted it around that 5.8-6k point. It had a Comp 280H cam, LT1 intake w/center plenum divider cut down 1 inch, 2" open spacer, 750 Holley Dual Line and 1-5/8" full length headers.

With the 340 having a slightly larger bore and shorter stroke I though it might have a little more torque range and quicker rev response.

Putting a center console in this car with HURST box/handle combo. Not sure how large the shift pattern on it will be but guessing it won't be as close of a pattern as that Pro shifter given the special shifter handle design.

Killer, were the 340's designed to safely/consistently rev that high from the factory?
