TPI 350 engine specs
I was wondering if anyone knows where I can find engine specs for the L98? I am planning a cam and head swap very soon, and I was wondering where I could get some info on that motor. I have some stock cam info, somebody please check this for accuracy please.....
Lift .413 INT .428 EXH
Duration 202 INT 207EXH
Lobe seperation 114.5
rocker arm ratio 116/116
I was also curious who makes the best intake runners? And finally, If I get say, Edelbrock heads, will I have to port match the intake for them to fit? Any additional info would be GREATLY appreciated. Thanks guys...

SLP makes the best runners IMO because you can always go siamesed with them later. Your cam specs are close enough, a degree or two off on duration is no biggy, LSA is 114, lift is about what you said, maybe a little more.
