It has been years but I own a TBI 305 again!
Long story short my brother has been working on some of my moms properties and houses and has alot of carpentry work. I stumbled across an 80s G-van 4 houses down from hers that had As Is $500 written on the back. Turned out it was an 87 with a TBI small block and TH400. The TBI small block turned out to be a 305. Only has 104K on it. It will soon get some abuse to make it run better. I managed to wake it up from its 2 year slumber in about 30 minutes and drive it to the shop. Despite having a 3.08 G80 rear it still managed to smoke the tires a couple of times on the way to the shop. I discovered it had a nasty tip-in knock when warm. Thanks to the base timing being set at 22° BTDC. I backed it down to 6°. Ran MUCH better.

Welcome back! I remember your name from years back. Sounds like you grabbed good deal, any plans for this one?

The 305 will live on though. It is still getting cammed but going into a 1980 Camaro.
Might seem we are doing this backwards but the Camaro is something we are going to finish to flip and sale and the G-van will stay around for a while. It will see some long road trips and some light trailer towing. I would not be surprised at all if the 6.0/4L80E/3.08 gear pulls down 20+ mpg highway in the Van.

Re: It has been years but I own a TBI 305 again!
We already made the decision to keep this 2007 6.0L DBW. I just did some ohm checking between a 2006 Hemi Ram APPS and the 2007 GMT800 pedal. Ohmmeter in hand it looks like it is pretty much spot on pin to pin and uses the same exact 6 pin connector. Bolted the Ram pedal to the GMT800 firewall bracket and screwed the GMT800 pedal bracket onto the G20s firewall. Physicall everything bolted in like it was made for the van. Whether or not it will work, we will find out when the 6.0L goes in and gets wired up.

Well you sucked me in with the TBI title Fast. LOL Missed this thread somehow.
Can't blame you for the change. Would be a good thread for Vanning.com.
Look forward to hearing more about the lil 305 in the '80.

The 305 will get a MTC-1 cam, new timing set, resealed and some long tube headers. Also a carb intake and a 454 TBI. Should push the Camaro around just fine. Probably going to use a 700R4 in it.

Re: It has been years but I own a TBI 305 again!
Why the 454 TBI, Fast? I get it'''it's bigger, more CFM. But I didn't think the just to the bog block TBI was needed until you were over the 300hp threshold. Are you expecting that much out of the old L03 on just cam and headers?
