Thank you I will check them out,

Thank you I think I will plan to replace the pump with High Volume -- If I can find one- they all seem to be for trucks with rear sump.

Thanks for the reply. I was tending think HV pump was best way to go, but there is so much controversy on the best solution to this problem.

I continue to slowly work toward getting my 73 back on the street. I recently replaced the 429 with a 460 stroked to 528. I initially had cooling and timing problems that are mostly sorted out thanks to the help of members on this forum. I have driven it a few times around the block, but...

I put a 180 degree thermostat in today and idled in gear 40min and only got to 215. Without stat I would have shut down after 20 min at 230. Did not get out on the street today, but thermostat seems to be a big help. I agree 40 degrees seems high, but it seems to tolerate it well. No knocking or...

No vacuum advance 10:1 CR ( calculated not measured) 18 initial plus 22 mechanical. Thank you for your reply

Thank you will and thermostat

Lower hose new and had spring, but I will check it. Reasonably certain head gasket is on correctly, ill probably check that last- thank you for the suggestions

Thank you for replying, using edelbrock water pump, fans are maradyne with shroud, tune may be a bit lean I am not great at telling lean from good unless very lean. Plan to get wide band o2 sensor to fine tune the carb. Will put in a thermostat first, but sounds like radiator may be next-

I just finished installing a rebuilt engine on my 73 mach1 and am having cooling problems. Engine is 429 stroked to 528 and probably is making over 650hp. I have a bigger than stock cam (254/260)so running a bit advanced timing which probably makes it run hotter. Factory radiator, no thermostat...

In addition to all that has been said -- I see you are here in South Florida. I had a similar problem and a big issue is that we have heat nearly year round. although is seems counter intuitive Ethanol in E-10 lowers the boiling point of the fuel and can cause vapor lock. If the problem...

Thank you for the explanation- very helpful

Thank you- I’ll try circle d- filled spec sheet for TCI. and Hughes with no response but it has only been a week

I threw a rod in my 1973 mach1. It had a. 68 429 thunderjet, I planned to go back to 351c it is a q code car, but I ended up with a 528 stroker. It makes 580hp 620 ft lbs so needed to rebuild the c6 as well. Problem is I can not get a good answer on torque converter selection. Car is street...
