Am I making a good choice?

TN-227XL 227/233 duration, .560"/.569", 112lsa


The guys at Combination Motorsports said its a great cam with some real good top end.

I'm gonna get the whole cam package with 1.6 RR's, 612 springs, seals, pushrods, guideplates. Then adding a new stock timing chain and gears, finishing up with a cam swap gasket kit.

 

anyone? I need some last opinions before I order!

 

Do it up!!!

 

Do you have a p/n on the stock timing chain?

 

pn: 10128485

 

I don't have the GM part number.... looks like dan got it for ya


I think I'm ordering mine through combination motorsports

 

 

Dont do it. Ill get my buddy to email me pics of what the stock chain done when he was trying to be hard headed and not go with a ex duty or the cloyes.

 

The only chain that cmotorsports offers is the EX-187 and it requires an electric water pump...

 

no, they offer several

GM-10128285 GM OEM Stock Replacement Timing Chain for LT1 $27.97
GM-10206039 GM OEM Stock Replacement Cam Timing Gear for LT1 $29.89
GM-10128346 GM OEM Stock Replacement Crank Timing Gear for LT1 $22.66

EX-187 EX Components True Double Roller Adjustable Timing Chain Set

CL-3145 Cloyes True Double Roller Adjustable Timing Chain Set $79.97

 

Thats strange. I just got an email this morning saying that they only offered the EX187...

Thanks for the p/n though

 

I'd go with the XE 233/239 But thats just me.
