429 on 75/25 race premium

well i got tiered of trying to get the 429 to idol right on the E 85. i was gonna try dennys trick and drill holes in the butterflys, but someone beat me to it, so i jetted it back down and filled it with 75% 110 and 25% 98 octane petroleum based fuel. funny thing is i hit the starter button and it fired right up and idoled like a champ at 1800 rpm. i think the metering blocks need to be opened up to match the jetting to run the E 85 and make it streetable, it was fantastic at wide open throttle. but horrible at a stop light. if i were going to soley drag race this car i would of left it alone. now we are happy, and if i drop a few ponies its still fast enough for any half minded person, and well thats me.

Looks good.
I would try mounting the coil away from the engine so it will stay much cooler.

That top vacant hole on the girdle looks to be a prime candidate and it would also allow you to mount it straight up. BTW, that is a nice looking engine compartment.

thanks for the advice on the coil, i will move it for sure!
