So, the transmission has completely failed. I have another vehicle, but this development moves the rebuilding up the priority list, perhaps out of DIY territory. Does anyone know of good machine/transmission shops in the Tampa area? Is it even worth farming out the rebuild when reman units can be had for similar money?
The trans can be rebuilt for less money then buying a reman. If its just clutches and a converter, expect $600-1000 for a bench build. (meaning, you take it out and take it to the shop). If they find hard parts damage (the input drum likes to get hairline cracks near the shaft) then expect price to go up by the cost of the parts, but there is not much more labor involved.
Hard to say about the engine since I don't know its condition.

The 5.0L Vortec is not really in the same ballpark as the 5.7L. When GM updated the 5.7L, they used heads that were way better. They trumped the L98 heads by a full 21% better intake port flow without adding much volume. Then they kinda said "well, we should do something with the 5.0L" so they sprinkled fairy dust on it and called it a day.
I always recommend not trying to upgrade a 305 in any way. Actually, I tend to make fun of people who do. The 305 is a small bore. It doesn't matter how much head work, cam work, or porting work you do, it is a very small bore with limited room for valves to take advantage of breathing. You can spend $1000 trying to make a 305 perform like a 350... or you could buy a junkyard vortec 350 for $500 and direct swap it in an afternoon. The 305 is only a little bit smaller than the 350 in displacement, but since the entire difference is in the bore size, it will always be a wheezer.
The "REAL" Vortec heads (castings 906 and 062) were found on 96-98 5.7L only. They used the same exact port that GM designed for the iron LT1 heads in 1993 used in B-bodies like Caprice and Impala SS.
There really is zero point in reviving and upgrading a 5.0L. Buy a 5.7L and drop it in. You'll be getting more power, more torque, more potential, and heads that can actually support some upgrades.
that's funny .. it's the same engine minus bore size.. 99% of the parts interchange... heads are exactly the same design minus valve size.. ware do you get your info? not to mention.. Few small mods like multi port injection. Accel distributor. Good plugs.and a tune that 5.0 will spank a 350 short order... done it several times.. but maybe mine is just special?????
The 5.0 and 5.7 Vortec heads are not the same. The 5.0 Vortec heads are the best heads that ever came on a 305 but they still don't share the chamber design with the 5.7 heads.
You literally joined this forum just to revive a two year old thread and defend the Vortec 5.0's honor? That's an odd strategy.
In reply to NickD :
I thought I got lost and wound up on Thirdgen.org for a minute there.

I do realize this is an old thread, but....where do I get my info? How about 30 years experience as an engine builder for names like Jesse James, Troy Ladd, and Mercury Charlie?
And yes. You're definitely special.
