More than happy to. Give me a bit. Waiting to get the data back from the shop.

My heads had a budget... stock valves and guides. I shot my $$$ on the bottom end to hold up to N20 shot. I ended up were you are restarting from @ .450 lift
Outstanding setup. I wish I had been able to do the coating you have done here. Some of the best engine **** I have seen in a long time. It should sing. What are you putting back in the 427 for cams? I have always wondered about these engines being over exhausted with the cams I am running right now.

this one is a 402ci.

Todd P has the Nasty 427ci.

Todd and I have gone back and forth on both our builds. I would have like to have done a 427 monster. Maybe on the next block setting in the shop.

My cams are SGC II/I .
I have a full set of both I's and II's I will do II's on the intake and I's exhaust. Todd is has done some of his own, he has a couple of pictures on the other site.

I saw those. Very nice. What are the specs on the stage I's and IIs?

SGC
Stage I .228 .228 .415 .415
Stage II .237 .237 .440 .440
Stage III .242 .242 .450 .450


From the lastest info on cams, the LT5 likes split cams better. I kind of wish I had a set of stage III's for the intake and would use the II's for ex.

I am wondering which port sizes are the best for each sort of cams.

Packing up for a move hopefully in a month or to Ill be set up and ready to tear into this. Have been told a few numbers via pm (thanks!) but have yet to see a sheet.

Not even sure I want to post them there will always be some tuner wanting to claim the same thing/better to sell their work. Sucks to know that so many pay BIG $$$$ and cant get docs on what their parts are doing, Id guess that would be standard fare..
We'll see.
