I just bought a small block out of a shed that turned out to be loaded with goodies. I need some help identifying some of this stuff.
The block is a Bowtie with splayed caps and a 1 piece rear seal. It is based on the 184 casting. I would like to identify the original part # if I could. The only stamped #s I can find on it are 148 on the front and 8.990x (deck height?) on the top pad. Suggestions?
The crank is a Callies with the word STEAL on it. It is a 3.75 stroke. Can anyone give me more info on this? I cant find anything on their website about a STEAL crank.
The pistons are Dished 4.125 and say TRW DRE-22 underneath. I would like to find a part # so I can calculate approx compression ratio.
There is a red anodized gear drive on it that uses 1 transfer gear set off to the left. I cant find a name on it. I could send a pic if someone thinks they know.
The heads are AFR 210s. They may be an older set. Lots of #s stamped into them. #s stamped underneath are 040 120 and 60cc (that ones easy). 2.080 and 1.625 valves. On top under the rocker cover on one side is 28 and 90, on the other side is
3, 15, 4, LW, and 2. AFR 210 on the end. I would like to find out the flow info on these and if they are the same as the current offerings or not. They dont have a D style exhaust port, more of a rectangle.
Any help with this stuff appreciated.
BTW this whole motor came out of an early 90s vette here in Central Fl. It is painted an unusual lime green color along with a bunch of other stuff under the hood if anybody here thinks they may originally have built it.
Thanks
Roy

 

Roy, the Callies crank should be a "Stealth" crank. That is what is in another forum members 383 I just built for him. As for the AFRs, the 210s are not D port heads. I have two sets sitting here and these are more or less square ports. You can probably call AFR to find out more about them. If the AFR heads are 100% CNC ported then they should flow about whats advertised in todays offerings. They really haven't changed much over the years. That is about all I can tell you about your find.

 

1.) You seem to know everything there is to know about the block except the main bearing size (400 or 350). I don't have a part number, but I can't imagone what more the part number could tell you.

2.) "STEAL" on the crankshaft would be short for "Steath", which is a Callis series of crankshafts.

3.) It wiuld be difficult to speculate on a piston part number without knowing the rod length (compression height of the piston). But you can measure the volume of the dish for accurate CR calculations.

4.) Obviously somebody's gear drive for the camshaft. Is the brand and part number important?

5.) You can't ASSUME that the heads are "untouched" since they left AFR. You will have to have them flowed to find out.

RACE ON!!!

3. The rods are by Oliver and marked 6.0

4. Inquiring minds want to know.

5. I think I was most interested in learning if the castings had changed much over the years or if they basically had the same potential as what you could buy today.

Thanks everybody
Roy

 

3.) Excellent rods, but you are still gong to have to measure the ccs of the dish.

4.) Keep digging.

5.) Have them flowed. Then you'll KNOW.

RACE ON!!!

 

CFI, when measuring a dish, how do you go about it?

I know 1ml H20 = 1cc H20 =1 cm^3 H20 at roughly room temp

But do you include the valve reliefs in the dish size or....?
TIA

 

Yes. Include any and all volumes below the top of the piston as part of the dish. You have valve reliefs that aren't inside of the dish???

RACE ON!!!

 

No, just asking a dumb question.
Gotta do it sometime right?
Thanks as always CFI
