I think your V6 Spider build is exceptional!

Looks like a lot of hard work went into building it.

The wheels...not a fan of them but they do give a stock/sporty appearance.

The wheels are enkei RP01's 15"x 8" with p225/50r15's in the rear and p205/50r15's in front. I was looking for a modern Ferrari like appearance so hence my choice. Stock wheel size is 13". I also changed the track on this by changing the offset as well as using a wider rearend. the change added 2" to the width both front and rear.

Thank you! I just finished with the brakes in the rear I am working on the front brakes next. The rest is all cosmetic and some minor electrical stuff.

Cheers!

Took the beast for a spin.. Still some refining to do.. But on the whole the engine runs great! Squirrelly as hell but that is part of the fun. I'm waiting on a master cylinder and muffler and I should be good to go after that..




It's a diamond in the rough.. 8)

So over the past couple of weeks I've been driving and tuning my 4.3L Vortec V6 powered spider. For a quick reminder..
The cam is a hydraulic roller cam from COMP Cams.
225 duration @.050 lift .. .525" valve lift with 1.5:1 ratio true roller rockers. I've discovered that it likes no more than 34 total advance @WOT. Whether it's a v6 with a roller valve train or a 4 cylinder with dual over head cams the tuning principles are the same I think. Also having the fuel/air ratio gauge really helped with my tuning efforts.. I had to swap to a couple sizes larger jets in the primary to richen the mixture as it was running too lean. But I also discovered I had the timing too far advanced which was showing on the gauge as too rich. The overlap of the big cam was tricking me into thinking it was necessary to advance the ignition timing further than it was supposed to be.
