cpi unit

anyone heard of a hopped up cpi unit for the w motor in a blazer?

doesn't exist.

HOW ABOUT ANY UPGRADES FOR THE BLAZER? Motor I mean, like msd ignition, throttle body spacers, headers, filter charger kits, or the CPI upgrades

MSD Ignition

Not really feasible upgrade when your existing ignition system will fire a 454 V8 perfectly.

TB Spacers

Can't use them on a CPI engine.

Headers

Very Minor gains for the high price. 2-3HP max. Our stock headers flow very very well.

Filter Charger Kits

Yes, this is a good upgrade if you go for a full aftermarket intake or even a K&N filter. Our engines need air.

Not Mentioned.

Muffler- Our Stock mufflers are made to be restrictive and quiet. Upgrading to a Ravin Z-series or a Flowmaster 40 will show gains especially in the higher rpm range.

Yeah I did not mention the muffler cause I just installed a custom flowmaster exhaust, I was going to get the MSD and stuff for fuel economy, and a larger spark, but if it is not needed than I will get the filtercharger kit from K&N!! I guess new tires will be coming sooner than expected! Thanks

No problem.
