Sorry, can't answer your question. But in case you decide to sell your radiator, please let me know. Here is my email address: (please take out the antispam statement).

Btw, does it have the built-in tranny cooler?

67 Camaro RS

I don't see that the size of the rad has anything to do with anything.....
The cooling of the rad depends on how long you plan on running this motor. Top fuel dragsters (6000hp) have NO rad at all.

yeah i know this is going to be a street car...fri nite sat nite cruiser, sun race car i dont really go far with it, and i only take it out at night so the traffic dies down, las night it was prob 55-60 degress and the car hit 170 cruisn at a light it hit 190........o and to that first reply, no it oesnt have a built in cooler, we mouted a huge external one outside the radiator support.

You can never have too much radiator. That is like saying you have too much brakes. Keeping your temp down is very important if you are running higher compression. When you are above 10.5:1 compression and you are running too hot, you are opening the door to detonation.

Yeah i know, i am cutting it close the motor is 10.5:1, but i am gunna have to try it, if not the becool is rted for another 100hp, if not i guess i will have to search around for a place that will make a custom monster one for me, or some other kidn of cooling trick.

That`s a lot of horses for a 10.5:1 engine. I`m running two different 502s using 454 radiators with no heating problems.

I have a 355 SB 12.0:1 that dinos 500+ with a griffin 4 core in a 69 camaro, with no heating problems.

190 is a normal operating temperature.

Griffin will make what ever you want.
And so will USA radiators also custom builds radiators.

uneed, please use the spell check, it will make reading your post easer, thanks.

imho you might wanna save the money for tranmissions and rearends with that kind of hp and usage. just my .02

uneedmorethen10s 10-17-2003 07:34 AM

sorry about the spelling, the car is prostreet, it has a 12bolt, with a strange spool, billet caps, richmond gears, moser 35splines, heavy duty yoke, and the TA adjustable cover, the tranny was a FB (th400 with the super rare screw for the center support to make it stronger) unit that me and my father went over again at our tranny shop, we put in blue line clutches, kevlar bands, reverse manual valve body, and we have a set of planetary gears for a box truck, they are straight cut and wine like a ***** and it also has our other special tricks with a superbell, it has a ladderbar(all fresh heiman joints and track locater) with qa1 coilovers, and the whole nine yards, the front and back are completely tied together and it has a 10point car to the Frame, the car and drivetrain wil handle it.

and for the motor it is a 555 10.5:1, Dart 360 with a heavy port and polish job, merlinII block Callie's magnum pro crank, crower buillet rods, JE pistons, gapless rings, and a comp cam solid roller, .270 @.50 duration and the lift is around .720 i dont have the cam card infront me, jesel shaft rocker, it has a ported and potmatched 4500series victor junor with a chuck nuytten dominator that is in the mail as i type this.

How about posting some pictures of your car.
I like to admire lots of good engineering


uneedmorethen10s 10-17-2003 04:03 PM

yeha sure i got a couple of pics of the car on the computer, i have a better quality pics, but this one has the tires up on my street tires with the 502 init, i was using a sportsman pro tire

i just tried to upload it n said it was too big even after being compressed with winzip, how else can i send it?

Resize the photo or increase the JPEG compression.

uneedmorethen10s 10-17-2003 07:25 PM

i tried i dont know much about says its 455 KB (466,371 bytes) compressed, and i tried resizing it but it cut out half the pic, can i double compress an image? or if you want pics i might be able to send you a pic

4 Jaw Chuck 10-17-2003 10:07 PM

Send it to Jon's e-mail and copy and paste the link to this page so he knows where to put it and he can post it for you, love to see your wheels.:)
