i sent you the link you asked for. check your mailbox. idk, he's fuel injected, and he's not through tweaking yet. go ahead and throw the bigger cam and new heads on just for $h*ts and giggles. here's a couple of links at something i'm looking at. leaning more towards the 454. nephew's fiance has a 427 that's been sitting for a while. but it's totally maxed out man. cam, heads, crank, pistons, the whole nine. he's only asking $1000. gonna take a look at it too to see if it's worth it.
