| RE: Machine shop advice for 428 FE rebuild? |
| By KarlJay - 09/04/2000 3:58:38 AM; IP 64.24.176.133 |
I just had a valve job done and paid $400. This included hardened exhaust seats and surfacing two sides of each head ($100), as well as $25 for seals. Get the hardened seats on the exhaust ($100).
The 428 needs to be balanced, 390,427... don't have the same balancing setup (390/427 are internal / 428 is external)
I had problems with the machine shop:
the valve job took a month, a rod was twisted and the shop said it was straight (the rod side clearance was not equal on both sides when torqued)
Be careful! If you just drag the heads,block... down for machining, you probably won't get any warranty. I saved about $300 and now I'm looking at having the crank returned and maybe replacing some/all of the rods. I only have about 50 miles on the engine and I've built about 12 engines before and never had this happen.
FE's like the dual pattern cam, I like the Crower ones and the exhaust needs more lift & duration. The Performer RPM is the only one ED intake worth having, the Performer is the same as the 390 GT 'S' intake, just made with alum.
pass up the forged pistons for most non-race usage. Spend the extra $20 on a hi-vol or hi-vol/ hi-pressure oil pump! I consider this cheap insurance.
Costs:
Bore: 120
general machining: $500~600
I wish I had let the shop do the whole thing, if you can get a 3year/30,000 warranty, I would consider that path.
Best luck, Karl. |
