just did that swap. more of a performance swap. in stock form. your going to be looking at torque monster. your going to like the 400's

[Billybob13]

i know 400s are powerful stock but the guy that built this motor is notorious for powerhouse builds blus the edelbrock intake and carb and hooker headers so im perty excited

[3r!c84]

start a build thread! keep us updated!

[Billybob13]

You should do about the same mpg as a 305/350 with the same mods

Consider yourself lucky, the majority of folks that complain about 400 cooling have inadequate cooling systems.

[Billybob13]

well were puttin stock cooling off 305 onto 400 ill have pics tomorrow today we unhooke everything and hooked 305 to cherry picker so tomoorow we put parts on 400 and drop her in and hook up new stereo and monday she gets to assert dominance lol

[Billybob13]

ok im a liar guys couldnt get before pics but i can get afters also motor still aintfinished because we have to take off tranny and replace torque converter cuz the one thats on there is for big shaft an my trans is small shaft but erything else is great new plugs wires, exhaust manifolds, water pump, gaskets, fluids, filters, etc. but more bad itll be couple more weeks and sorry bout takin so long to repost but computer was havin seizures

[MadManAndrew]

Wouldn't like...the fuel pump be the heart, and engine be the muscles?

[Billybob13]

well i guess that would be more accurate

[Billybob13]
