i built a mild chevy 350 for dirt racing , will the module in the hei distributer make the engine miss a little at idle?????
also
i have the inital timing at 8 degrees, after running for a little until it gets to 200 degrees temp i turn i off and let it sit for about 8 minutes and then i try to start it but it is alittle hard to start. is it the timing or somthing else????
thank you everyone.

P.S. does anyone race at clay tracks and if so could you tell me what tire pressure you run, i would like to compare, thanks

8 degrees is not a lot of initial advance. It will not cause a hard start problem at that setting. I suspect you either have a starter that is heat soaking or you need to address better wiring to the starter.

aceofspades49c, An HEI module is pretty much either good or bad. Hei's are voltage sensitive so make sure you have good voltage(12.6-13.6) at the BAT terminal on the distributor. Batstar70

what tires? type of car? wieght? also you should lock out the advance and set it at 36 degrees.otherwise make sure you have about 36 when all in, do not use vacuum advance.

I assume a street stock?

What tire rule?

[aceofspades49c]

theres no tire rules except you cant run Wrangler tires, its called spectator class, its pretty much any fullsize car with a v-8, you dont need a roll bar and the top speed is about 50mph in the straight aways. some guys just bust the glass out of a beater and race it but i strip the whole car and move the battery, and Help the engine a little its real fun.

it cranks real good but just doesnt like to fire right away, and also the fuel lines are away from the exhaust, i have a feeling its the ignition , because even at idle it will misfire once in a while. i also have a camaro with a build 305 and when it is ran for a while and nice and warm it fire up right away, thanks

So you are using a street tire?

With a weight of 3400 pounds I would start with:

LF 10-12 RF 18-20

LR 12-14 RR 16

If a tire rolls off the rim up the pressure a few pounds on ALL four. SO you don't lose the cross. Roll it in easy and let the car roll over before picking up the throttle. Letting the car nose over the right front to long kill you exit. Run the widest tire you can by rules, increase stagger with air pressure if you weld the rear. Disconnecting the RF brake will help get the car in on the tacky.

if they allow a roll bar or cage by all means do it. Not only for safety but it will also stiffen the chassis and make it handle better. Check out the dirt forum.com under pure stock /bomber tons of info.
