i figured the advertised duration should be on this paper... maybe the .344 & .348?
Kenneth HI Performance is the guy that built it
The engine was built to be a DD and it is also my only car. so i told the builder that it had to be a reliable motor. Also it would need to be able to drive from houston to San Antonio (about 2 and 1/2 or 3 hours) if needed to. And i would also like around 450 to the ground. Now i know that 450 to the ground and a DD car is a hard combination. but he told me that he could do it so i believed him. now i am unsure

on a side note. i called my motor builder (again) and he is going to get me a flow chart (my father lost the old one, i never saw it, just heard about it) and the advertised duration. should have it by Friday. yall have been a great help. i will post up the numbers when i get them.

ok i Know that it took forever. but i finally got the advertised duration on the cam.. it is 294/305. It has been real pain trying to get info out of this guy,he has been really busy building motors. and I am still usure of what compuression to tell pcmforless to tune the computer for.

I am really thinking hard about putting the 1.65 RR on the motor also. I would end up with .567 lift on the intake. << any more thoughts on this?

well.... I still dont now what compression i should tell pcmforless to tune the computer for. its getting close to that time 
... but i guess i still dont have enough information about the motor anyways... also is there any reason why i should not be able to run 1.65 RR << hardware wise, i just thought that somewhere i hurd that WE (lt1's) could not run 1.7's. that is probly just because of the stock heads or valve train..... maybe?
also is it going to be deadly if i dont tell pcmforless the EXACT scr. what if i tell them 10.5, and it is really 11.1, will i lose HP and if so is it going to be like .5 hp or 10 hp.

I think the SCR might have some effect on timing, but tell them you don't really know and that way they will make a safe-side tune for you. You may not be at max power, but you won't blow it up either. I guess if the best your builder can do for you is 10.5:1, then that's what you tell them.
The reason most LT1's don't run over 1.6 RR is because of valvetrain geometry issues. Anything over that and you should get some shaft mount rockers or just a bigger cam.
