forged 416 build
 

the timing chain broke and caused a fair bit of damage, that coupled with my aversion to failure, I'm hopefully going to build a motor that I can get more than 25,000miles out of.

failure and diagnosis here http://www.camaro5.com/forums/showthread.php?t=382495

the plan
 

1st tore it down and assessed the damage
Good Parts: block, heads, clutch, rockers, rods, a couple of pistons and the crank could be reused, but it needed some work
Bad Parts: chain (duh), cam, some pistons, most of the valves, crank needed some work, oil pump, metal everywhere..........

with the above and the plan to keep road racing on weekends and having the car as a true daily driver we decided on a few necessities and a few good to haves and some things just because

forged stroked bottom end with a slight bump in compression
custom grind on a 3 bolt cam motion core from BTR designed for torque and sustained high RPM
keep the 660 BTR springs (tested good)
reuse the comp cam trunions (checked good)
LS2 "bow tie" tensioner
C5R Katech chain and factory gears
another high volume oil pump
CNC the intake and exhaust runners on the stock heads
polish the combustion chambers for heat control
head studs
oil pan baffle
external oil cooler
ATI 10% under drive balancer
auxiliary oil temp gauge
under hood fuel pressure gauge
data logger for smart phone

all I have so far is the pan baffle and the heads

the pace should pick up after this weekend

Sounds like a good plan! Subscribed and looking forward to seeing your build progress.

be safe this time go with a nice Fluidampr harmonic balancer to help engine vibrations and a nice timing chain would help and also driven racing ls30 oil,,,, that's all the advice I can give, and your old cam did have a lot of wear and metal shavings around it in your pics. Good luck. I do know that a comp cam gear drive has been made also......

Subscribing to the build.

Oh I like this!

Subscribed.

This should be GOOD! Subscribed!

You have my attention....

Gorgeous oil pan baffle setup.

for the balancer/damper I went with the builder. he had not heard anything bad about the fluidampr, but did not have any personal experience with it and said he and his buddies all run the ATI. I'm a lemming

C5R chain is in the plan, I'm not an early adopter, so i'll pass on the gear drive......

thx for the suggestions!

sooooooo true, it is sweet looking. I know that I am not an early adopter, but this looks so good and I don't see how I can go wrong with it. this definitely falls into the "just because" category of purchases!

Saw that gear drive at SEMA....very interesting but not sure I would spend that money. C5r chain is well proven.

Give us a call if you need help on the short-block or short-block parts. With over 200 crankshafts in stock, 200 sets of rods & probably 60 sets of pistons I bet we have something to get you going. We can even machine the engine for you. With the TSP short-block setup you get cnc digitizing & blueprinting to make sure your bores, decks & cam to crank correlation is correct. That's something nobody else in the LS industry can offer!!
