10 Day Magnum Swap - '65 Dart 270

A cam will be a noticeable difference. Right now you have about .410 lift and maybe 198^ @.050. If you dont want to mess with valve springs then the only cam I know of that will work is our stage I cam. Its .454" [email protected] and works with pcm. If you do a flash, you can use more duration but factory springs are limited at about .450 and even with largerr springs the factory heads will need guides trimmed around .480 ish(depending on who you ask). If you get EQ's with our stage II spring kit, you can go all the way to .550. Our stage II cam is .520 212@ .050.
Some quick approx #'s
stock heads w/ stage I cam, throttle body and pcm flash 300hp easily probably more like 325
stock heads with stage II cam and springs, guides trimmed, TB and pcm flash 340-350
EQ's w stage I cam and springs $1100 for both 330-350hp with TB and flash/ wouldnt be surprised to see more.
EQ's Stage II cam and springs, ($1300 for both heads and cam), TB and flash 350-370
or go with .533 215@ .050 or even .544 [email protected]
