Re: 90 RS 305 TBI to Vortec 350 Swap

I used Edelbrock headers #350-68723 at Jegs.com.


Stock Vortec 5.7L heads are only good for ~.480 lift so it depends on your current cam lift to if you can upgrade to 1.6 rockers. The 2 stock...

Re: Anybody Have Dyno results for this Motor

The 1.6 rockers are well worth it but you will have to do the ".550 lift mod " to your Vortec heads as your lift will jump to .496.
