I had TWO BeCool's leak -- in my Nomad -- never again.....

I use AutoRad now. Actually - I'd use ANYTHING over a BeCool... :D

I'm running the $1200 BeCool also and so far its treated me and the car well. I'm running 620 hp at the crank.

Greg, which BeCool did you use?

Whatever crossflow they sell for a tri five chevy... polished etc...

Both leaked in the exact same place -- where they GLUE their tanks on... I no longer use anything where the metal is glued... They call it epoxy -- I call it GLUE. No thanks to those tanks! :D

How long ago? 1956? Ha even Ron Davis was using epoxy 10 years ago. I agree though, I wouldnt buy a brand new epoxied radiator.

I went back and read that he has a 400 Bowtie block, Most of the true Bowtie blocks don't have the steam holes

A "crossflow" radiator will make a big difference too

I have had both Davis and now AutoRad
 

THe Davis and AutoRad both are excellent, and not inexpensive. radiators. I ran duel fans on both controlled by my ECM I got the larger diameter tubing in my new AutoRad. The target market for Davis seems to be a bit more industrial for HD racing and the AutoRad same quality and cooling but the extra touch to the street look and finish.

my 2 cents

Good ideas on the Radiators.

I had never dealt with a BT sbc before, and this issue was baffling.

Do you think that a "Cross Flow" radiator with the killer Mark VIII Fan would still be a viable option?

Those fans with a proper housing on it I believe to be about the strongest around.

Fan CFM is only important when you're not moving... and it's more important if you're running A/C... and if you add an automatic transmission to that... then you have a lot of heat to deal with.

Personally I like dual fans -- and I've been controlling them on my cars with the Spal PWM fan controller. It adds cost - but really works well - especially if you're running A/C.
