looking to install an lt1 cam in my camaro with an 89 TPI 305 lb9, I know some different years in the lt1 cams had different specs, some small differences whats the best year if any? and I want to change my Valve springs as well, should I buy valve springs for a 350 lt1 and put them on my 305 lb9 heads or stock TPI Lb9 springs.

 

anything??

 

Cheapest GM LT1 springs are the Hotcam /ZZ4 springs @ $36

You need a 305 expert to say whether they are a drop in fit on your 305 heads like they are on LT1 / 113 heads

 

lb9 and iron l98 heads should take the same spring...

 

Stock lb9 heads with an lt1 cam, what springs with that combo

 

Do i go stock lb9 springs or stock lt1 springs that all i was wondering

 

here is the 94-95 LT1 cam specs

Duration: INT.205/EXT.207
Lift 1.5 RR 447/459
Lift 1.6 RR 477/490
LSA 117

If you use 1.5 ratio rockers your still at or a little above the max. If I where you I would use an aftermarket valve spring and go with 1.6 ratio rockers to get that much more out of it.

I do not know if stock LT1 spring will work on 305 heads. If I were you I would place a phone call to a few local performance shops that do LT1 and TPI cars and get thier opinion. Chances are if it can be done they have done it. I distinkly remember LT1 cars complaining about weak valve springs though so you may want to go another way with the springs

EDIT: here is the link to the page I got the cam specs from http://www.ws6.com/faq/4_2.htm#ch4_2aw

 

I was just thinking of going with stock 350 l98 springs brand new and the lt1 cam, i dont want to go 1.6 rockers

 

I have a set of valve springs, roller lifters and a used LT1 cam that has already been modified for small block use. I also have a stock vortec 350 cam

 

Is this setup still for sale?
