Good luck with the build man, I really hoped you’d buy my L98 since i need the cash LOL but thats ok 400 is a nicer motor i guess if done right. As long as you run a good low temp thermostat and a decent radiator/big dual fan setup, you’ll be fine with cooling with a stock like motor. Just run the fans on the whole time if it acts up but i dont think it will. You’ll have to find some better heads for that motor. i think you have 493 heads if its a 71-72. Else it could be 624’s which are SHIT or 882’s which are also kinda poor heads. Either way they all pretty much are weak and need replaced sometime down the road. Good luck with getting that thing running ---

Why would a 2 Bolt be better than a 4 bolt? ---

i was always under the impression that 4 bolts held the main better than 2, but a converted 2 bolt to 4 bolt with splayed caps was the best for strength, even stronger than factory 4 bolt. Atleast thats how it works for 350 blocks from what i’ve seen. ---

Atleast thats how it works for 350 blocks from what i’ve seen. The 400’s bigger main cap (Diameter of 2.65 journal crank compared to 2.45 for a 350) causes the outside bolts on the four bolt blocks to actually weaken the block in the main web area making them more susceptible to cracking under high stress. ---
