My name is Phil and I live in Naples, Florida. I am a machinist working for a local Aerospace Manufacturing Plant.
I am glad to have found this site with like minded Impala enthusists. I will be glad to ask for and offer any advice I may be able to.
Use to have had a 66 Imp.which I restored then sold and also rebuilt a 76 Corvette with a 396 from a 68 chevelle and still have.
Now have a 67 2 dr. Impala which I hope to keep for a while. It,as of 02-25-09, has been under resto/mod.
A professionally 489 BBC built by Collier Machine of Naples, Florida (they specilize in Big block Chevys) is installed. Wound up having the 454 bored out .030 with Eagle 4.25 stroker crank and rods and Mahle 10.2 cr. pistons. The cam is a Comp Cam 11-208-3 with .520/.520 lift and their magnum roller rockers. The heads are Aluminum with 310 flow rate. Gasket matched the Edelbrock Air gap intake w/Edelbrock 750 (the heads did not need it). Engine cooling is done with a large aluminum radiator. Exhaust is a set of Hedman Elite headers with 3 inch pipes and a x crossover with Magnaflow turbo mufflers.
I have: repaired all rust areas on the body and have it in primer and used copious amounts of POR-15 wherever I could so rust will not be a factor for many years to come. Trans is a 700r4 by Monster Transmission A custom heavy duty driveshaft to hold the estimated 515 hp and 570 ft/lbs torque(according to Desktop Dyno). Rear is a 12 bolt with Eaton posi w/3.55 Richmond gears and Moser axels. Front suspension is Global West tubular and 4 rear tubular control arms are by Pure Muscle. Sway bars are Helwig (front and rear). I put 4 wheel disk brakes on and plan to go to 13 inch disks up front. Interior has a 1/2 inch sound /heat barrier on the floor and firewall. Climate control is a custom after market air condtioner designed just for the 67 Impala. It is a great compact unit,they have fantastic service and it is easy to install by yourself in a day or so! The hardest part is to pull the right fender to get at certain items though. Other than that it is all a pull and replace job. If you have a old AC unit or none at all check it out at &vxp=mtr&hash=item5addd273e1
The usual three gage oil,water,volt cluster is under the dash.
Right now I am having health problems and the resto is at a standstill. I hope to get back at it soon.
Hope to hear from y'all.

Welcome to the Team Phil!

Did they use a block out of a pick up truck? Reason I ask a lot of big block specialists on the gold coast are marine engine builders for cigarette boats that like to race off shore. as far as that goes did they use a Mark IV (two piece crank seal) or a newer Gen V block (one piece crank seal). You can tell by looking at the timing cover and the fuel pump. If it has a fuel pump and ten bolts holding on a steel timing cover then it is a Mark IV block (or a Gen VI service block if it has only six bolts on the plastic timing cover). If it has no fuel pump because there is no place to bolt one on then it is a Gen V one piece rear main seal four bolt block with flat tappet hydraulic lifters from the factory (though it has all of the casted iron in place, but none of the machine work done to accept a factory hydraulic roller cam if you ever wanted to convert it over).

The bare block was a MK IV which I purchase from a friend. I had it compleatly rebuilt for plenty of torque down low to move such a big ride. It has a very flat torque curve from 530 at 2000 rpm to 570 at 4500. I will send some pics if I can figure out how to use the uploader.
