And all 1996-2013 marine Vortec 350 engines engines, which use the same L31 Vortec 350 heads are used with a 196║/206║ 0.431"/0.451" 109║LSA, with 1.5:1 rockers.
Then we have the Ramjet 350 crate engine which uses that same 196/206║ 0.431"/0.451" 109║LSA roller cam, but this time GMPP(now CPP) decided to use the 1.6:1 full roller rockers which now puts lift up at 0.460"/0.481".
Clearance when using Comp 787-16 retainers which are designed for Beehive springs and the GEN 1 and GEN 1E and GEN 2 valve stem diameters.
Suggested install of valve seals.

|jexrod||I finally separated the engine and tranny, found the flex plate in good order. Started the engine with no tranny or exhaust attached and sounds like the noise is coming from the engine.... Haven't been able to adjust the carb, car starts immediately but dies when I step on the throttle. I hooked up a test light and it looks like its about 12-14 btdc. Oil pressure at idle is around 52. Sounds like a very loud backfire, any ideas on what to look for?|

|jexrod||Thanks, I'll inspect this weekend... hopefully the damage is visible and I'll start the tear down.|

So I finally dropped in the engine and tranny, had a hard time getting the gas from the tank to the carb. After a fuel pump swap the car stayed on for less than 10 sec and this clanking noise started. It got dark soon after so I was unable to do any major investigating. Any ideas on what it could be? Car ran for about 2 minutes and I shut it down.

|jexrod||I dropped off the driveshaft yesterday to be cut. I ended up installing the 700. Pretty easy swap except for slight clearance issues on the tunnel. Servo was rubbing. I ended up using Autolite 103's for spark plugs. Had a difficult time sourcing u joints (the zone, p boys) stores had a larger u joint specified in their system. The drive shop will source the right ones. Just installed the TCI lock up kit inside the pan, now trying to figure out how to wire the external harness. Any feedback on how to install the included vacuum switch? Ideally after much research I would like for it to unlock with the foot brake and vacuum switch?|

|dwwl||I would have to agree, that 66 impala is a heavy weight. Then you got the glide tranny. No matter how many ponies you get from the 327 cubes, that light weight nova even with 275 horses, will walk away from you. If you put a 350 tranny in that thing, it will be like driving a different car. If you want it to really move out, Put 4.11 gears in rear with a 700-r4 or 200 4r tranny and you'll have lower gears for street use and highway gears for the open road. Just a old guys opinion. Which those overdrives autos would of been around thirty years sooner. Got 355 cubes-200 4r tranny- 3.73 poss rear. what a mover.|

|jexrod||Any suggestion on spark plugs? Do I look for a vortec engine plug or a 327 plug? gap? Thanks for the help trying to gather everything for this weekend. I'm using a generic HEI distributor.|

Kudos to you on the follow up, we don't see that enough around here. PLEASE keep us posted. I don't think we see enough vortec headed street builds here. Theyre fine heads for the street. Can you imagine what guys would have went through to get Vortec head performance; at an over the counter price. In 1968; these would have been KILLER heads. They still are

Finally, got some progress done on the car. I'm sure its the same ol' story, got busy and a lack of monies stalled the project. Anyhow, dropped in the 327 engine and 700 tranny this weekend and will try and tackle the accessories this upcoming weekend.
Any guidance on how to measure the driveshaft? I know I have to get it cut a couple of inches.
