Single Rail only, Good to see your still kicking around

Water pumps can be a cause of the overheating, Some of the cheaper ones don't work well just creating cavitation and air bubbles, best fix it to get a electric water pump which controls the flow, we used these on the old 1948 Bentleys for weddings and are the best thing ever.
 
My old Clevo used to over heat with a cheap water pump, I then upgraded to a QCP or something brand which had the Wheel instead of the fan blade type and that along with Rad clean fixed my issues. could sit in traffic on a 38deg day and while it got warm it never overheated.
 

Check the block hasn't been shaved as well as this will increase the comp way to much for pump gas.
 
I had a 351 030 (Block deck to 0) and CC Heads and it was a pinging nightmare with unleaded, even 98 was only a little improvement. Change to a wilder cam made a little difference but it then suffered on take off, increased stall and that helped but was still not fun. We estimated it had 11.8:1 comp as on Avgas it was a weapon, you could advance the timing from 0 to about 10degs and the change was awesome
 
Mate had the engine after me and he replaced the heads with a set of shaved & Ported OC reco heads and back to the original Crow cam and it was a total different beast, no over heating and ran really nice as that was just over 10.3:1 compression

50mm bricky chisel along the edge where it chips over the gutter. Sit edge of the chisel along the trim piece you want off then carefully tap away with a hammer  till it releases. Keep working your way along resisting the temptation to just twist it off once you've got a run going. Take your time and be gentle cause once they are farked theres no bringing them back.

Hi all just an update on times ran 11.04@119.10 mph today  and 6.96 to half track.
