Timing Set With Big Block Crank

[red450ih]

For those who have used a BBC crank in a W engine without turning the crank snout down, what timing set set did you use? Is there such an item? As it stands I am considering getting a Cloyes 9-3601X3 and having the crank gear machined to fit the BBC snout size.

I would like to retain the BBC size snout if possible. I already have a timing cover and harmonic balancer that will work with the large snout.

I believe Bob Walla has a timing set for that application. He is on this site as "region rat" , or BWR raceparts.com.

The timing set in my 482 is from Lamar Walden Automotive. I have a 454 LS7 crank with the big block snout.

Thanks for the replies. I'll look into the suggested parts/companies.

Another question, what crank pulley do you fellas use with the BBC harmonic balancer?

I plan to use a BBC 7" balancer and hopefully an original water pump pulley.

Will a 7" balancer clear the water pump itself? I'm sure 8" is too big but thought 7" is/was cutting it close.

303Radar,
An original 409 harmonic balancer is 6.75 inches. The extra .250" will not cause interference issues.

I plan to use a BBC 7" balancer. I would also like to use an original water pump pulley with this set-up if possible.

Should be BBC pre 1969 or called short water pump style. Factory originals for High Performance would be deep groove on everything and 4x the price of low performance ones. Deep groove for over 5,500 RPM to keep from riding up and rolling off.

Thanks models916, I'll find one of those and give it a try.

Only the short water pump. Not sure about BBC or SBC?

Thanks models916, looks like I'll need to find a GM 3921923 part number pulley?
