Which BBC to get for my '87 V30?

No diesels. The truck is a gasser and I want to have FUN with it! Horsepower and torque! ;)


Your right, diesels arent fun, nor do they make hp and torque... :rolleyes::haha:


there isnt anything erotic about pumping so much black smoke at the stoplight that the mustang next to you cant even see to drive- much less race.

Nor does the 20mpg, 700ftlb tq 12 valve cummins make me smile when I pull a 6% grade with a 10k trailer behind me....and im still grabbing gears.

No, your right. a cummins 12 valve would be a boring engine....
 
While the numbers sound good, the time and labor along with the added expense and my dimwit knowledge of diesels will stick with a gasser for this truck. Its so much simpler and easier to bolt in a BBC and go.

I think you're missing the point or I'm not explaining myself very well.

I want a simple bolt in and go. I've read numerous threads and posts on the cummins swaps, both here and over on the Ford forums.
Now while those who tackle the task attempt, and succeed, at it, I applaud them for their time and patience to do so and also at the fab work necessary to get that big pig in the bay.
I just don't have that kind of patience or knowledge to tackle a chore like that. So I just wanna leave it at a BBC and call it simple and done.

Remember, I'm doing it the KISS way: Keep It Simple Stupid. ;)
 
I understand what you're saying there. but you have no idea how a BBC pales in comparison when you want to lay some rubber or yank a load. and with the dollars you are actually talking about spending. maybe look into it some. I mean theres a couple 3 different places that offer bolt in crossmember/ motormounts for the 73-91 SFA trucks.
 
Bumping back to the top for more opinions on crates.

I'd like to look into getting started on this project this coming fall.
 
I think the TBI is gonna choke any decent crate engine you buy...I'd go with the HO 454 and a good Q-jet from JET.

I just built a 454 stock bottom end, '74 BBC with 990 square port heads, port matched dual plane edelbrock X427 intake..... (yes its a vintage old intake) predates anything that says "edelbrock performer" A comp cams 280H. It should haul ass in the Z28 as is until I put big slugs and a forged bottom in it.


Ya I wouldn't put TBI on yours either. I'd get a solid crate "whatever" and a good carb for it and go.
 
Why...you think TBI is really that good? I sure don't. It's simple, but beyond that i have pretty much nothing good to say about it.

I like FI, but not TBI.

Well, can of worms open I guess. Define better...

Direct comparison to a well built Q-jet IMO the TBI loses in all but two catagories. Cold start ease, and altitude compensation. Reliable operation at crazy angles is near enough to a tie as the Q-jet will also run at some ridiculous angles. Both have exceptional off idle response, both get about the same fuel mileage.

Modify the engine a little and tell me how much you like TBI. TBI has a lot of little ghosts and quirks too.

I have TBI currently, it's OK but my 454 will be going in with some mods and a Q-jet. Much easier to tune and compensate for cam, heads, exhaust etc...

I have a 1988 V10 Suburban that has TBI that has been modified a couple of different ways. It runs fine. It could use some tuning and a custom chip, but it doesn't have to have one.

It consists of a 1990 IROC 350 short block with forged flat top Speed Pro pistons, Vortec heads, a 1995 LT1 camshaft, GMPP Vortec TBI intake, 1.5 roller rockers, headers, 2.5" dual exhaust. The vehicle was originally equipped with a TH700R4, and now as an SM465. I changed nothing in the computer when I did that swap.

I'd say that is more than a little.

Pistons, short block...irrelevant. 1.5 roller rockers...again irrelevant as the stock ratio is 1.5:1. 2.5" duals, again nothing to phase carb or FI.

So basically you're running a very mild cam, better heads, headers and a manual tranny with the stock chip.

Add a decent cam, and we'd be seeing you in the FI forum asking for who is best at burning chips and the fun would really begin. I'm not saying TBI can't make power, I'm saying power can be made without hardly any sacrifice, without any chip burning, and without any headaches by choosing a q-jet. Factor in that tuning is just so much easier with a q-jet and it's just a no brainer for me.

If I had the cash I'd surely go with an aftermarket MPFI set-up, until then I'll happily run a Q-jet and enjoy some freedom when it comes to cam choice.

Interesting readings, guys. Keep them coming.

I hear ya on the Q-jet, Rene. And yeah, I'll take any Q-jet over any Holley, any day.
