How big is the cam? From your description it sounds like you have too much compression and too small a cam to run anything but straight race gas. It should pick up over a tenth in the 1/8 upping the timing from 27° to 34° (I know mine picks up 3 tenths in the 1/4 doing this).

i'm pretty sure you need a cooler plug. on NGK's lower numbers are hotter so a 6 is hotter than 7.

NGK -7 are more for race and -6 is more for street and you are running what i think are BPR5EP which are street only, very hot plugs

'6's are still to hot go with a -7 or heck with that compression maybe even -8

but you are way way to hot right now

BP6ES is probably good send a message to OU812 / Brian at IMM see what he says

flyfish That is true.
I had brian at IMM spec this cam out for me with the concept of stretching my P.O.S. 11 inch TQ with the high altitude that i live in. Its a HYD roller 562/550 lift 242/[email protected] on a 102 intake center that i advanced 2 degree.

That makes me fill better about it being "just" a spark plug heat range!!!!

No i stepped up to a BCP6ES(5/8 Spark Plug) (Box number 4930) with my new motor.
I don't know if one step colder is going to be enough?

Hate buying 12 spark plugs(4 for dialing in the fuel/timing) and to find out i need 12 more of even a colder plug............

Think i will order one of each, and do some more testing.(7 and a 8 heat range)
