water around plug?.. hydrolock?

sopes

leaking coolant temp sensor ? looks like it starts higher than the plug, also is that a broken head of a exhaust bolt ? Gm has 13mm headed exhaust bolts instead of the 10mm headed bolts that are more durable and wont shear off

sopes

Also get a under drive pulley to free up some HP other than that you are on the right track with your list of goodies

Not fun. Had to do a head bolt and rocker bolt that broke on me. Head bolt was easy. Gave up on the rocker bolt and took it to a shop. Didn't want to ruin the head with how far down it broke off in the hole.

thats what im afraid of is drilling to far or making it harder to get out fortunately I know a few people that do motor work for a living

Would 28lb injectors be sufficient enough?

ls6 cam would be a waste of effort IMO. go ahead and get you a after market cam that's mild and you will be more happy. Don't be one of those guys that wished he would of went bigger. if $ is a issue just find you a nice used cam from a good source on here.

What duration would be a mild cam?

madmike9396

iTrader: (29)

mid 220s and upper 500 lift should be fine.
Ls6 cam specs are... lift .479/.467 duration 196/207 LSA 116

In a LM7 5.3 like I posted before Ls6 cam results 376 hp @ 5900 rpm
389 tq @ 4500 rpm

factory 5.3 cam done 353hp @5200 rpm
384tq @4300 rpm

all up to you is it going to be a drag car or you want a healthy street car ?
