I will be putting a 97 350 vortec in my car and was wondering if anyone has some tricks up their sleeves to crank up the ponies.I will be using a carb and installing an LT1 6spd behind it.Any suggestions would be welcome.
thanks:thumbsup:
Steve

383ci's, 9.0.1 comp, and put a procharger on it:unibrow:

Edelbrock makes a nice E-tec head for the vortec stuff and eagle makes everything you'll need for the bottm end and pistons are easy, Je has those to.:thumbsup:

Stroker crank, different cam, rpm intake...

Tons of vortec builds on the internet.

Take a look at this link, http://www.chevyhiperformance.com/techarticles/49083_inexpensive_roller_cams/index.html

I have one of these with very low miles, and I'm planning on building it pretty much like the one in that article. My present 406 is worn out, so I'll throw one of these together while I decide on building a better 406, or moving on to an LS based engine.

Unfortunately, L31 blocks are not machined for mechanical fuel pumps, so you'll need to set up an electric one if you haven't already.

I have an older engine block with a 280H flat tappet cam at 10.5:1 with vortec heads and an airgap and I can vouch that it works well. I also have an LT1-style 6spd behind it and hills still aren't a problem in 6th thanks to the vortecs. Truck heads are nice for the low-mid range grunt.
