Thanks for the compliments. I know not everyone likes modified cars. My opinion is, we only live once and if we own it then we should be able to have our way.
The motor is a 347 stroker with Edelbrock aluminum heads that were ported and flowed by a race engine builder. Based on what I told him I wanted, he selected components, built the motor and dyno'd it too. I didn't want a crazy cam with all the HP high in the rpm band and unusable, like a drag motor. So the cam is middle of the road. It is a hydraulic roller. It dyno'd at 466hp @5900 rpm and 463 ft/lb of torque @4400 rpm. It makes 400 ft/lb by 3500 rpm. He said it could have made at least 550hp with the right cam selection.
Oddly enough, I am using the same Griffin radiator as with the 260 that had headers and an aluminum intake only over stock. It always ran at 200deg on the gauge and got to 230-240 in traffic with a stock diameter flex fan and stock shroud. The stock shroud is not shroud, but more of a hand protector. Being open on bottom kills it. I also had an entry duct, horn holes blocked and a sheetmetal shield from radiator bottom to the cross member. And it ran that hot with around 200hp.
Now I have the same rad, same front air duct and horn holes blocked, but I made a custom aluminum fill shroud, have a Dales front end so now I have a 15" diameter flex fan, a Maverick fan pulley and I installed an 11" pusher electric fan with a thermostat for in traffic. I haven't had it in traffic on a hot day yet. But it has not gone over 200 deg on the gauge (which is wrong). My infrared thermometer says the intake or heads are 180-185 when the gauge is close to 200. My thermostat is set for 180 and it doesn't come on until the gauge gets past 195. Is this common?
I also ceramic coated the club headers to get that heat out of the engine bay and I wrapped the H pipe and mid pipe to the mufflers to try to get that heat out of the engine bay through the driver compartment and out the back. I'm sure that the hood with the exit scoops helps matters too. I would be curious who here changed nothing but adding an LAT hood and what that did to engine temps in similar conditions.
