so I took my intake off the engine in the 84... pics and video

[Montehall]

I have an electric fuel pump.
my motor was TBI - Crossfire.

I think it depends on the year, IIRC, the head design changed in 86.

Shorty headers are inexpensive if you get a good deal on newer engine.

The exhaust pattern didn't change, its the angle of the intake manifold and bolt pattern.

exhaust went from the square to the D pattern in some year

but the intake is the same for SBC through 86.. at least that's what that intake I bought and returned was supposed to fit.

but yeah, there's the head I have, and there camel hump heads, centerbolt heads vortec heads, bowtie heads, etc...

That is exactly what I mean and I would bet if you show up with cash in hand he would bargain with you. As far as intake fitment there are only three intake bolt patterns for the small block. First is the original, second is identical to the original with the exception of the bolt hole angles in the center two holes and all you need to do to make it fit is elongate the center holes so the bolt will go in then use a flat washer to cover the enlarged hole. The third design however is all by itself and does take a special intake, (Vortec) this manifold only has 8 bolt holes and they are straight up with no angle at all. His asking price is not bad but if he can be talked down you would be in great shape.

and except for the two hour drive...

Gen 1 SBC, as far as I know, used iron heads up to mid 86 on the vette, then went to aluminum, but the intake didnt change until 02 with the LT1 (gen2 SBC).

In 87 the Trucks got TBI, and used TBI up until 96 when the Vortec 5700 came out, the vortec heads had different ports, intake mount bolts, etc..

Id think, a truck TBI 350 from 87-95 would work for you....

That said, I dont know of any TBI 4 bolt engines...

[Fastguy]

Read midnight 85's post, it covers the intake differences.

[RED-85-Z51]

The engine is my truck is a crate reman 350, I think the guy paid like 1500 for it installed, new heads, new crank, new rods, new seals, bearings, cam, water pump...oil pump, distributor, all sensors, thermostat...and it runs great.

3.42 gears on 33" tires and it still pulls an 18 foot trailer no problem, has like 25K on it now, no leaks, or problems.

i wish it had more cam, but the previous owner opted for a stock TBI cam...

Not a bad price for reliabilty...he got it through Oreilley autoparts.

Good thinking ahead..

I doubt I would have even thought about that myself.

The block may not have even been machined for the pump completely.

It still may be OK, but would be well worth checking into before spending for parts in the wrong directions.

Just me... but I would still just clean it out well, and drop some used, or new lifters in it and try it first before spending lots of money and time fitting a new engine in there.

I have an in-tank electric fuel pump. that's not really an issue for me.

You are running a carb right? What are you using to get the high pressure injection fuel pump down to the 4-7 lbs of pressure that is all a carb can handle?

a fuel pressure regulator.
Holley adjustable with return. I have it dialed to 5.5 psi

[Midnight85]

Well I guess I worded that question in a way to show my stupidity. I asked because I have known people who tried to use the in tank pump on a carb with out a regulator. I never was much good early in the morning. What have you decided to do?

[Montehall]

I'm going pull the oil pan... although it's supposed to be thunderstorming today, so I doubt it'll be today.

oddly enough, when I first got the car, the DSPO didn't have a regulator on it. he just crimped one of the hard fuel lines... I fixed all the stupid issues like when I replaced the head gaskets.

[Midnight85]

How many miles did you put on it before regulating the pressure the right way? The reason I ask is he could have been lucky enough not to have the carb leak externally but still leak down into the engine where it would have gotten past the rigs and washed the oil off everything which could bring you to where you are now. That would certainly explain the debris you found when you pulled the intake the excess gas would have been washing down the cylinders causing excess wear. This all just a guess but it is possible.

[Montehall]

I probably put about 100 miles on it before I installed the regulator.
but that was probably 16 months ago.

[Midnight85]

Well, we can speculate all we want to but it won't tell us a thing so I guess it's definitely time to break out the wrenches. When you get the pan off, if there isn't anything readily visible post some pics of the inside of the pan and of the bottom end of the engine. With all the sludge you found up top the bigger shrapnel, if there is any, may be stuck in goo in the pan.
