Information on a 340 for my 69 dart
so 68/69 has different tc wp pulleys does it fit 70 up block ....(would like it to look 69)
if it
has to be 69, then you're looking for 1 year only timing cover. the waterpump is the same 65~69. this will also entail using the correct 22" radiator ($700) and shroud ($200) fan & clutch ($325)
then next question do heads have different cc chambers think i would like to be around 9.5 to 1 ratio not like i need crazy big valves
funny i thought all sb mopar would use the same timing cover stuff
not sure but i had a set of 273 comando rockers think they are gone now many years ago
heads any of the 340/360 "letter heads" will suffice for the trainspotters-- X, J or O dealer's choice on those and the attendant valve sizes. so get ready to drop real dough there, something in the vicinity of what a decent set of aluminum aftermarket heads would be once everything is said and done.
factory would've be HD hydro rockers, not commando adjustables.
anyway, you can sort the compression ratio out on the build so i wouldn't be worried about chamber size.
have to have manifolds
not that matters now but what color did they go orange 70?
the other thing is factory air cleaner ...did it have a heat riser ?
340 manifolds are nice headers prices, so expect to be there for that. the headpipes and rest of the exhaust system is readily available, but figure on dropping about 2G's there and a little more if you want "correct" tips.
factory air cleaner: repop ones are about 150, then tack that on again for a pie tin, if you can find one. so you're 300 on that. double it ++ if you want NOS or good condition OG.
the 340 intake manifolds are sought after in the resto crowd so you'll be battling their wallets. you can usually scoop one for around 275 or so. then cough up anywhere from 75~350 for the correct AVS carb. you'll need all the throttle brackets and kickdown **** too, so there's another 200 or so. and the correct valve covers are gonna set you back anywhere from 100~200+ depending on condition. AMD has 70+ ones at 200 but real heads would notice the difference.
getting the pulleys, distribuitor and wires right is no big deal. that stuff is out there and a drop in the bucket comparatively speaking.
340 was orange in 70
thanks for letting me spend about half of your 15K budget. this didn't include obtaining a motor or rebuilding it!
