Building a High Tech 440ci High-Compression Dry-Sump EFI Small Block - Engine Power S10, E11-12

[@robertshoff333]

I built 440 cu. in. small blocks in 1972 for my late model modified circle track car. Bob Gillean at Dearborn Crank shaft did the 4 1/8 billet crankshaft. Dave Crower ground the small base circle camshaft. I designed and machined the custom 4340 connecting rods and fabricated the 180 degree headers. 4 1/8 by 4 1/8. Many comments on Western Pa. Circle track websites. Clate Husted was my driver.

Man I love these big small blocks. I used to always run 350s, 383s and I still own a couple but I really like my new 434. In my C10, with a power glide with 3.42 gears...it's an absolute handful. It runs n/a like my old 383 on a 125-150 shot. And to top it off, it's now a hydraulic roller cam and I love not having to lash valves all the time. I talked to Nolan at Isky Cams and told him what I was building, he spent a good while talking to me and he recommended the perfect cam for my combo. Just enough low end torque to be streetable and tons of midrange and top end power. I plan to wire and plumb my new nitrous express kit this winter, the engine is built for spray

Better bay-to-bay breathing on the OG small block vs LS blocks. Splayed 4 bolt mains are plenty strong enough to handle what these guys are building it for. Plus, since the block is OG small block, there's less fab to be done to bolt it in most things that originally ran small blocks.

[@Timmayytoo]

@@p.d.3192 I had the same reaction as @bobqzzi and your suggestions did occur to me, but at this point there are tons of LS parts and it seems like they had to have several custom parts made to work with this hybrid block.
