1965 Impala BBC I/S

impstocker · 06-28-2013, 09:45 AM

Had a 1968 Impala original 427/425 car with matching #'s, pulled that motor out and built a Stocker with a 396/325 , Jerico and ran I/S at 4095 pounds. ran 11.70's best, but never really flogged it. I sold car to collector who restored it back to the stock 427/425 car, lliks great. I purchased all the race parts back from him, rear end, ignition, motor ect., now i am building a 1965 Impala with the same motor combo to run I or H Stock.

I love all of those Big-Block full size cars! Get busy!

Thanks Billy, my brother Ed ran a 69 Nova in V/SA with the 230 in the eighties with Joe Huestis, Div 1 car, they could never get it yo run like your car though! The Impala is apart, working on the frame. Any input would be appreciated.

Corner full of race parts! 12 bolt with spool, 4:88's

What trans and clutch do you use?

What reliability do you get out of them?

Also how does the rear hold up?
Is the 12 bolt fairly rugged.

Seems some racers have little problems with 4sp's
Others seem to have horror stories and go to Auto.

I believe the heads are a different casting number for the year change.

Re-weld the upper rear susp. crossmember to the frame while you have the body off.
Otherwise you'll have to cut holes in the floor later.
Ask me how I know...

Double gusset the lower trailing arm brackets to the frame >> <<

Thanks Mark for this good information.

My 1969 Impala is having a full restoration.
When we pulled the rusty frame off noticed a bunch of cracks.

Have any other suggestions?

Thanks Mark, I am know about that problem with that crossmember pulling out, I gusset and plate all the suspension points in the rear, also a run a crossbrace from the roll bar to that upper crossmember. I did that with my 68 Impala, probaly overkill, but I never broke a part leaving up to 6500 RPM off the line.

Dan, I used a McLoed Soft-Lok clutch and believe it or not just a 14 pound aluminum flywheel. I see some guys out there insisting on using a 30 pound steel flywheel for "inertia" to help a heavy car leave, but if your making HP the car will drive thru that. (one fella runs a 3300 car, making HP, insist on using the 30 lb flywheel, the cars leaves way too violently. Thats old school clutch thing. I used the Jerico 4 speed w 3.09 (?) first gear. Best aftermarket piece ever made, never broke, still working today. I had over 90 passes on that tranny and sometimes I "forgot" to use the clutch!

Dan , the rear is a 12 bolt from a Impala, they have the bigger wheel bearings and axle tubes. welded the tubes to the housing. Moser spool with rifle drilled axles and star flanges. Cover is a girdle with the braces. 4:88's in it now.
