tsp224r vs. tsp224xe...

the only difference is lift .581 compared to .566, how much difference in performance should i expect to see? the only reason, i plan on running LS6 springs that i already have and the 224r is a bit too much lift.

 

the 224r will make more power under the curve. I would go with that and get the PAC 1218 springs from SDPC for $125.

 

Thats what I did. Installing tomorrow. Everyone told me this would be the way to go. After I get them in and tuned I will let you guys know.

 

im going to run LS6's i already have them... this is going to to be a budget cam swap, so im looking to do everything including a converter for around $1000. i really had my eye on this cam, but oh well. i will be deciding on something from TR

 

Be careful running those LS6 springs alot of cams have a much to aggressive ramp rate and those springs are prone to failure with those nice high lift aggressive lobe's! an extra 100$ now may prevent pulling your head(s) and replacing valves. just a thought

 

Also the ls6 springs are only good to 550 lift I believe... The 224r has a different lobe then the xe one is es a exr lobe, one is the xe lobe

 

yep true. . .some of the aftermarket cams have way more aggressive ramp rates that the "LS6" cam and the "LS6" springs cant control the valve harmonics that great and may cause broken springs or valve float.....comp 918's FTW!

 

i know i have read a lot of positives and negatives about the springs. i have decided to go with the TR220/112 with the LS6's. thanks

 

also FWIW. if you can get yourself a good price on the Ti retainers, they are 5 grams lighter than the stock steel retainers and worth it. good luck with your cam set up

 

why are you so set on the ls6 springs? the ls6 springs were meant for a stock cam, not something with lobes like the tr220.
