HRS 710461-10 273 226 .525 Garrett Ellison for 9.5 340 post 23 110LCA

340 cam 279 210 .429 2899206 intake @.006 stock early 340 was a 9.5:1 class motor

so is this a 9.5 or 10.5 build?

stock exhausts post 34

What PRH says post 45

Garrett post 46 Magnum heads, good suggestion if not no 1.7 in this budget

Post 49 Quit trying to fit the cam to the head flow not going to happen without high ratio rockers and or mushroom lifters

Match the cam to the rear gear and how the lady wants to drive it- be happy

also no 108 with stock exhaust – stick to 112 or 110 if short cam

stock exhaust hates overlap

agree with PRH has anyone cc'd these heads?

post 80 XE 274 may be an old UDHarold grind, same problems as the 268
