Hi everyone I recently had my 400 built to about 400hp at around a 10 to 1 compression. 62 heads ported and valve job with roller rockers and all that block was bored .30 over. The cam card was lost so I'm not sure exactly which one it is but it is a comp cam with 480 lift 232 in and 237 ex. Rear was rebuilt with a 373 posi. 400 turbo trans was just rebuilt also with shift kit. So the question that is currently driving me nuts is what torque converter to go with. My engine guy told me to go with between 2000 and 2500 and I'm am just looking for some more opinions. Someone else also recommended a 2800 stall. Is there a certain brand I should go with? This is my first build and don't know much about these things and want to make sure I do it right. I would also like to know what a good tire size would be for my 15 x 7 honeycombs. Also with the engine being on the high compression end I want to make sure the cooling system is as good as It can be. Could someone give me a recommendation for a good fan clutch? Thanks for the help. I have been working on this car for 5 years and trying to stockpile all the parts I need to finish it this winter then come spring I will assemble everything.
