Engine options for the 1962 Biscayne
Permalink  
 


I'm looking into engine options for the 1962 Biscayne build.  I am quite fond of the "W" engine options, and have  several choices.

 

One is a date coded 1961 tripower 348.  I built it with a 409 crank (quarter inch stroke) and BBC rods with Ross forged aluminum pistons.  Heads are the small port 1147s.

 

Another option in a 1965 date coded 409 truck block with standard crank, BBC rods and KB-Ikon forged aluminum pistons.  This one has the big port 583 heads, with the 881 dual quad intake.

 

We also have a nascent FI setup that was partially adapted for a FI system.  That would also be set on the big heads, in this case, the 690 casting.

I vote the truck block 409 with dual quads.

I guess it depends on how you plan to use the car. What are the compression ratios (fuel needs) of the two motors? What cams? Either one would be great but there is something about a dual quad 409! The things songs are written about!

Tom,It’s great to have a choice of 3 engine setups! I love them all. From a Visual point of view, my personal opinion is the F.I. Setup. I’m sure that any street driving would have its challenges though.Looking forward to what ever you choose- if you don’t like it you have 2 more to choose from. No wrong way to go lol.

I now have moved forward and am going with a 1965 truck bock (409) with the big port heads (583s) and a dual quad intake.

The truck block has been fitted with new KB-Icon forged aluminum pistons on BBC rods using the stock stroke 409 crank.

The heads were done right 12,000 miles ago so we took them apart, cleaned everything up, lapped the valves and reassembled. Screw in 7/16" studs, one piece SS valves.

I decided to go with a cam I had in a previous stroker build. Up top I have a factory GM 881 dual quad intake and carbs. They look great but don't perform as well as some newer castings. We're running one of those new McQuillen intakes (dual quad) on the BA409 drag car, but those are kinda pricey for a street car ($1600). So it's either the stock GM intake or another I have in the shop.  I had acquired a rather rare M/T cross ram for the big port heads in a trade and if I had a hood I could cut I would consider that just for the looks (and the performance!).

Cheers!

Tom
