Well I had some antifreeze in my car, but now it froze because I didn't have enough. Seems like the car won't crank... There is no leakage anywhere under the block. The car almost kicks but nothing... Where do I start I need to somehow flush the coolant system.
 
I believe the thermostat got hydrolocked and the water was boiling over in the engine. It was not allowed to get out because there was too much steam/water in the radiator so it boiled over blowing the headgasket. I guess I'll find out for sure tomorrow.

I thought I had antifreeze/water mixed but it ended up nt enough antifreeze... I'll keep this post updated with pictures.

Does anyone know if the TFS R and TFS street share the same lower for the 351 and 302?

The R and street lowers are different. Trickflow only makes an R manifold for 351 based engines. You can not use a 302 lower on a 351, the 351 block is wider but i'm sure you know that.
 
Yea i know. I was just hoping the ports would be the same because they look relatively similar. I figured there would be a difference. Oh well. I'll just do headgaksets if thats all thats wrong and be cheap about it till i can afford to go up in cubes. College > me. Co-Ops start soon and i'll be hopefully making more money than I am now.
 
The R ports are a bit bigger. I put my street heat gasket up to my R intake and the street heat gasket really interrupted flow! The bolt pattern is the same I think so it will bolt on to it.
