stroking my 340 to a 4--
Listen to the above. I back-havled (lol, this is 1987) first. Shortened Dana, 4 link, tubs. Then picked up a 727 man rmb, and a 3500, with only 13 runs on it. Then custom drive shaft. Then finish the cage (that stops body flex). Then discs on front. Cell, 6 an fuel line, etc. Batt in trunk, firewall, ammeter bypassed, mallory 7al, etc.
Now ready to replace the 340 with a 408.
Start at the rear, if you can't get the HP to the ground, you can't win. I think that is a quote from Don Garlits.
