Ok so here is the engine I bought off Craigslist for $500 ( I Paid Full Asking Price ) that I picked up last Saturday oct 5th 2019 I bought it from an older lady ( her husband bought it new in 1976, he passed away oct 1st 2018 ) in North Jersey the story was that he ordered The engine before he even had a car to put it in. A fall occurred on the truck while in route and dented the oil pan and valve cover and radiator was damaged it was complete carb to pan ( It was then taken apart to check for any other damage and was never put back together however he did buy all new GM gaskets to put it back together ) was ordered and shipped thru kenne bell also was listed as having stage 3 heads wasn't sure what I was going to come across after driving almost 2 hrs way. Needless to say it came home with us ( me and my father ) and inspected it once we were back home, also she gave us all the paper work for the engine turns out it's a 70 block dated for November 21st, I was able to make everything but 4 items out the total cost was 3901.70 in Sept 1976 with a 1500 deposit and 2401.70 on delivery, ( $17606.11 in today's money according to online ) over the years the muffler,b4b intake, stinger s4 system and 1000cfm TQ went missing also included was a 67 switch pitch trans and kb149 converter included ( never used both from kenne bell ) we are going to put it together and put it in a 70 stage 1 ( not numbers matching ex race car ) we are going to finish putting it together and see how it runs, if any one has any info I would love to learn as much as I can included in pictures are what I could make out on the receipts I have a set of kenne bell roller rockers, headers, B4B intake already to go on it plan on getting it in the car within the next 3 weeks Things I could read off the kenne bell papers Block and Crank $150 Machine Work $275 Balance $60 Transmission ( 67 Switch Pitch ) $300 KB 149 Torque converter $175 Stage 3 Heads BARE $490 Stainless Intake Valves $66.40 KB Mark C Cam $75 Headers MISSING Muffler MISSING Radiator Damaged in Shipping KBCVC Valve Covers Damaged in shipping Carrillo Rods KB32302 $535 1000CFM TQ carb MISSING Jahns FP Series Pistons forged alloy $196 B4B Intake MISSING Stinger S4 ignition system MISSING KB100 High Rev Lifters $33 KB103C Ultimate Adjustable Pushrods $45 KB107 Heavy Duty Trick Valve Springs $30 KB112 Hardened Valve Locks $6 KB113 Perfect Circle Valve Seals $9 KB116 Special Crank Gear To Advance Timing $12 KB125 Rod Bearings $26 KB126 Main Bearings $26 KB127 Cam Bearings $11 KB131 Perfect Circle Moly Rings $60 KB178 Timing Chain $11 KB179 Hardened Cam Gear $11 KB 182 Timing Cover With Oil Mods ( can't make out Price) KB184 Racing Pulleys MISSING KB181 Large Oil Pickup $10 Some Prices Are Hard To Read and May Not Be Correct GM part numbers that I have found Head Gaskets 1236030 Intake Gasket 1394705 Oil Pan Gasket 1396972 Stage 1 fuel pump 051P40804 AC GM Pf-24 Oil Filter Timing Cover 1246055 Oil Filter Assembly H-1382760 Harmonic balancer 1233832 S4 Crank pulley 1375142 Water Pump Pulley 1375141 New GM Start ( Didn't get #s Yet ) Also got Koni Adjustable Shocks Front And Rear Still In The Process of Cleaning and Lubing Everything Up Will update as we Go
Did the lady happen to give you a flow sheet on the heads? KB farmed out their head porting to some guy and I was wondering what the flow numbers were for the Stage III KB heads.
Nice! What a deal. That sure was a high dollar operation to get it all done by KB! Shame they didn't keep some WD-40 on everything. Still a great deal. The heads flow very good and are worth that much. Should run 11's with no problem. Looks like they skimmed the deck a smidge. I'd check out how deep the pistons are in the hole before using the .020" steel shim head gaskets to make sure you have at least .040" clearance. With those pistons and gasket compression is going to be 12+ I'm sure. That seems to be a MKc118 cam which won't bleed off much pressure for use with pump gas so be prepared. The rust on the valve springs is a bit iffy but that cam is not a monster so they should hold up. Anything more serious and I'd change them.
The good thing is he did turn it over every couple years, used a flat edge and came up with .20 from piston to deck with a feeler gauge everything came up very well even the valve springs and took off all the loose rust on them. I can't find the ratio of the pistons but I'm thinking they are 10.25 to 1 the catalog just says UPTO 14 to 1
Im not sure to be honest the lady didn't know much and only thing on the paper work is. "machine work"
OK so the Pistons are .20 in the hole. My stage two engine was decked and the pistons with Valve reliefs is just about even in the hole compression is 13 1/2 to 1 I say you're close to 11 1/2 or more compression depending on what gasket you use and exactly what the use of the car would be for street or race.
Mostly street driven almost 7k miles last year may run it once in awhile want to run 92 pump gas is the plan. do you think that would be fine to use?
