Just as slow as before mods..

Yes you can take all the plugs out or you can take only one out yes having the carburetor held wide open during this test will in effect give you a more accurate result. The old style starters don't crank as fast therefore people like to take all the plugs out AKA rid the resistance. Don't worry about the cranky people. As mentioned.. around 145lbs is what you expect from a bone stock 318 / rebuild, slant 6, 360 etc.. 8.1 or about. If you have less than that... we will need to look into the 'why' . Someone was mentioning stock cam or RV cam or something like that but I'm not thinking you have an RV cam for some reason not after all the money you put into it. To stick a white box cam in there would be pretty half-***
Ok here's what I got as per receipts:

1. Machine work for resurfacing heads and valve job, repaint engine
2. Carb - 500 cfm Edelbrock AVS2
3. Cam - Grind 260H RPM 1200-5200

basically a 340 cam and a question mark on the bottom end.

but to your point, should still be 145-ish across

i'm still thinking that getting the carb and timing dialed in might wake this sucker up. but given the rest of the chicanery i'd leave nothing to chance and verify everything. oh and the whole WOT test and trans kickdown needs handled.

i dunno, maybe he thinks it should put his eyeballs into the back of his head when the loud pedal goes down? it's only a 318 with a 340 cam and 3.70's so not like it's gonna yank the tires, but it should still be good for a pair of black stripes.
