what temp do you guys run on the street?????

OH YA one more thing I live in Florida (it's hot here all year long)

That about normal for in " in traffic" driving with a Hot motor.
It does cool down when running on the open road correct? Do you have a shroud for the fans? Tell us more, Charles

Re: I'M HEATING UP
 

Did you drill the steam holes in the heads and use 400 gaskets before installing them on the 400 block, that and then 4.155 bore make the cylinder walls thin, i'm also guessing that you're running an octane booster because 11.5 with a steel head is a little high for pump gas. So i'm guessing you'll not get it to run much cooler than 200 degrees in traffic.

Zip.

PS, i'm getting ready to drop a 406" in my 1998 Sonoma stepside backhalfed

Ditto on the steam holes. not really required for race only but street driving is a must.
