Got them milled to 62cc with up graded springs, along with:

ARP Head Bolts
SVO 30ibs injectors
Crank Bolt
Head Gaskets
Exhaust Gaskets
Pushrods(7.350)
LS7 Lifters LS2 Guide Plates
All this is goin thru 6 speed, LS6 Intake Pacesetter LT catted Y with FM Merge collectors

222/228/115 cam Crane 1.8 RR I am hoping to make 420rwhp+ SAE with 400Ibs TQ.

I should expect them in about 3 to 4 weeks.I let you know the results.

How much hp and tq do u think I will gain from my setup??

I gained about 60 hp and 60 ft lbs of torque but that was with just some patriot heads, with the afrs you should be looking at gaining a little more than that.

Be more specific pls. You mean I will gain 60rwhp in combination with my cam headers exhaust set up?? Tony said between 30-40 rwhp!! Am I missing something. They are milled to 62cc though.

your expectations of 420 when everything is finished sounds about right. When you are done with everything listed it should be around that.

Congrats on the purchase! I've got some 205's milled to 61.5cc that will be going in over the next couple weeks. I've got a bit bigger cam going in though and shooting for 440RWHP. Probably have to flycut too but that's ok with me.

What do u mean flycutting??

It's where you cut a small clearance into the top of each piston to allow the intake (or exhaust) valve to clear without hitting the piston. Optimum minimum clearance is 0.080" on the intake side and 0.100" on the exhaust side. Preliminary estimates show my intake valve clearance will only be around 0.060" but I intend to measure the clearance with the clay method to be sure. If it's really around 0.060" or less then I'll cut each piston by about 0.020" to have at least 0.080" clearance. It all depends on the cam and type of heads (milling the AFRs reduces your clearance between the valves and pistons) but running a bigger duration/higher lift cam reduces it even more.

Nice bro, cant wait to see the results! I will be doing the same swap with the same parts, except my heads are stock 243's off a Z06. Nonehteless, I hope you put down some good numbers and hit the 400TQ mark, thats what I am shooting for. Pred Z spec'd my cam.

420rwhp should be doable but that cam and intake will be holding you back especially with a shiny set of AFR's.

Well I figure I will build up from here see where this set up takes me, then if not, thinking about 232/240/117 with a ported fast intake. I still cant believe I still paid that amout for them. Bought them directly from AFR, I must really like my car and this hobby. Oh yea car is paid off too Just last week hahaha.

Hey detoxx your car looks awsome man!!
