Hi everyone.
Haven’t posted in an awhile but still read here on a regular basis. I built an engine over the last while after reading a lot of information on this site even through I am a truck guy. This forum is definitely the best for small block information.
Anyway finally got time to test the engine this weekend. Test went well at the start, and ended poorly but it could have been much worse.
Build is a 94 magnum block, stock bottom end all freshened up with a hone, new rings and bearings, deck cut 0.008 just to square it up. With the 0.028 head gaskets it worked out to around 9.3 static compression.
I have the OG NZ EQ heads with 2.02 valves, bowl blended and port matched to an Eddy LA air gap intake and a Holley VS 750 carb.
Cam is a Hughes SER1822ALN-10 with their premium roller rockers (purchased before the price went up) just to make me feel better about the fast ramps the cam has. Cam is installed at 105 ICL.
Goal was a nice street cruiser that had lots of pull for a 78 Warlock that will have 3.91SG and a A500 OD transmission with 28.5” tall tires and 2500 SMR stall.
We made 3 or 4 dyno pulls and the results started repeating so the rings were seated. We then took the RPM range up and things were going great. For the test we had a 1 inch open spacer during the pulls. We wanted to see what taking the timing from 34 all in to 36 did, but when the engine was at idle something sounded off all of a sudden so the dyno operator shut it down right away.
Long story short I had an intake valve stuck and bent a push rod. Piston has a little mark but hopefully I got lucky. The EQ heads did not have bronze guides, but the heads had been reamed by the person who did the valve job. Needless to say the heads will get guides as part of the repair.
See below for the one of the runs we did. No jetting or adjustments had been done at this point and we felt it had more left. I know these types of builds are posted a lot on here, so I wanted to share some numbers anyway.
Hope these help others.
