Engine update:
Thereโs a change up Iโm going to be doing on the 355cid for the 86 C10, the intake, going to take the B&M roots off and going with the Edelbrock 1551 E-Force 122 Chevy Supercharger, itโs less maintenance and has the Eaton rotor assembly in it (๐ฌ๐๐ซ๐๐ฐ ๐ญ๐ฒ๐ฉ๐), the belt is smaller unless I can get a 9 grove update to look more aggressive, it will only produce 5-7lbs depending on compression compared to 8-10lbs B&M 144, Iโve built many engines using the 144 and never used the Holley 122 being itโs a newer style, Iโll have to research everything to see how it might perform with my setup, the heads and camshaft, Iโm sure some changes will be made.. some probably asking themselves what will the upgrade to the (Holley) Eaton H122 cost?? On the high side $7K low side $4K depending on changes.. the supercharger itโs self runs around $3600.00, you can get it for the Vortec engines it costing about the same.. Iโll either sell the B&M or keep it for another project donโt know yet..
Here some more information on it
Edelbrock 122 Supercharger Kit part #1551 for 1955-86 302-400 CID Small-Block Chevrolets is a positive displacement supercharger that is capable of producing 500+ horsepower on a small-block Chevy engine. Satin Finish
The Edelbrock 122 Supercharger Kit part #1551 for 1955-86 302-400 CID Small-Block Chevrolets is a positive displacement supercharger that is capable of producing 500+ horsepower on a small-block Chevy engine.
This system utilizes the Eaton H122 rotor assembly for maximum efficiency in a compact package.
The compact design may potentially fit under the hood of most muscle car and street rod applications.
Testing resulted in a peak of 507 horsepower and 487 ft-lbs of torque @ 5 PSI on a 350 CID with 9.5:1 compression.
The Edelbrock 122 is designed for use with factory style belt and pulley configurations.
Will not work with aftermarket serpentine pulley systems and will require the use of a long-style water pump. Each kit includes the supercharger assembly with Eaton internals, intake manifold, drive pulleys, belt, gaskets and all necessary items for ease of installation. Does not include carburetor, so you can use your carburetor of choice. This Edelbrock supercharger is intended for 302-400 CID Small-Block Chevrolets equipped with long water pumps and stock style bracketry. It's designed to utilize the factory accessory drive belts, in conjunction with the secondary 6-rib supercharger pulley drive system. Manifold height: A-8.50in., B-9.75in. Carb pad height: 9.125in. Satin Finish.
Iโll do another video of the B&M 144 before I remove it, if I do sell it Carb not included
Iโll make videos on this change as things progresses
