Hi!
Can i have some advice of these cam,who is the best for me,they are used and the price are the same.
Tpis 262/270 adv.duration,470/490 lift or the XR269HR "Extreme" Hydraulic Roller Camshaft, 218 / 224, .495 / .502 112 LSA.
I am going to run the stock heads and a Holley miniram, for now anyway.Thanks for any replay.
Anders.

 

The lift "may" be more than the stock heads can handle. Allen

 

i know a guy running a .560 cam on "stock" heads...theyre stock, just not for an L98...i would do some research on that...what kind of driving are you going to do? is this mainly going to be a street car with some track time? we need more info...

 

Do you mean the TPIS Miniram or the Holley Stealth Ram?

 

what engine do you have, 5.0L or 5.7 is it tune port injected or carb, if its a tune port the ecm will give you problems, and the car will not run right, you will have to have a special ecm made or burned, if the car is carb just look out for the lift, could run into bad coil bind, seen it happen before, recommend installing roller rockers, may have to change the valve springs

 

its hard to find a cam that meshes perfectly for a tpi thats why id go w/ the tpis one, theyre designed to fit the tpi setup the best you can.

 

with a cam choice that big, you may have to get a stall converter as well

 

Hi guys and thaks for the replay!
The goal i try to reach is a car that have a lots of power (say350 flwhp),its not a daily driver car but not a strip car ither.
It is a Holley stealthram.
Its a 5.7 TPI
I already have a stallconverter.
Do you have the speccs for the TPIs cam?
Thanks
Anders

 

If u want to pay more for something you can duplicate as well as, if not better, than get the TPIS cam :-)

They gouge you on anything.

Shop around some.

Do a search on some cam choices meember here have used.

Summit and Jegs can get you any Comp/Crane/etc grind you can imagine. Also Crans/Comp etc have toll free numbers for cam help :-)

Just keep in mind if it is primarily a street car, I would go smaller, if it is a toy/strip car, then go larger.

Personal preference on a 350, I would stick to 212-220 on the intake side and 215-225 on the exhaust, again this is preference from stuff I have put together and I have driven my cars in all conditions. Make sure your heads can handle the lift though. Stock heads will almost assuredly require at the least better springs.
