Small Block Chevrolet - Gen III/IV - LSA

If you're looking to swap an LSA or LS engine into your vehicle but your engine didn't come with an alternator bracket or the factory setup is too wide to fit your project, Holley has the answer. The 20-166 Bracket tucks the Alternator in closer toward the engine when compared to the original LSA accessories, giving more clearance where needed. These brackets look truly at home on the LSA engine, so much so that nobody will realize it didn't come from factory this way.

NOTES: Torque M10 bolt to 36 ft./lbs. When wiring the alternator, install the included 197-400 plug into the alternator. Next, connect the yellow wire to switched voltage that is "on" when the key is in the run position. If the vehicle has a "charge indicator light", the yellow wire can be connected to that circuit.

Excellent quality - great buy! Looks sharp!
Size: Large, Color: Gray, Size: Large, Color: Gray
Great quality - this is a medium weight coat. Perfect as a car coat but too thin for cold winter days if you had to be outside for long periods of time. The fit is just perfect. Purchased a size large for a man 5’6 175 lbs with a small belly so peacoat double breasted look - looks great! Lining is standard and the grey color is very appealing. This is soft feeling coat made to look like wool without the heavy rougher wool feel. Only issue is that the coat comes packaged in a small bag and so when you open it the coat it totally wrinkled. You can knock out the wrinkles in the dryer with a wrinkle release dryer sheet or use a garment steamer but honestly the dryer trick is the key.

Long enough sleeves for a tall guy
Size: Large, Color: Green
I’m 6’3” and skinny, and was very impressed to find the sleeves were long enough for me in a large! The overall fit of the coat is boxy or straight, while I would have preferred a slimmer cut, I’m just so happy that the sleeves fit! The liner is nice, interior breast pockets on both sides are super convenient, and I love the green.

A Timeless and Stylish Pea Coat - Perfect for Winter!
Size: X-Large, Color: Wine Red
The quality of this pea coat is exceptional. The wool blend material feels soft and luxurious, and the craftsmanship is evident in every stitch. The coat is well-constructed and designed to withstand the test of time. I have been wearing it throughout the winter season, and it has kept me warm and cozy even during the coldest days. The classic double-breasted design of the coat is timeless and versatile. It adds a touch of sophistication to any outfit, whether I'm wearing it for a formal event or a casual day out. The notched collar enhances the coat's elegance and provides a polished look. The fit of the coat is excellent. The sizing chart provided by the seller was accurate, and the coat fits me perfectly. The tailored cut gives it a flattering silhouette without feeling restrictive. It allows for comfortable layering, so I can wear sweaters or jackets underneath without any issues. One of the standout features of this pea coat is its attention to detail. The buttons are well-placed and secure, and the lining is smooth and comfortable against the skin. The deep pockets are a great addition and provide ample space for storing essentials like gloves or a phone.

Really nice for the price!
Size: XX-Large, Color: Brown, Size: XX-Large, Color: Brown
This jacket is a really nice find for the price, my bf is 6’4, 350 and the XXL fit really well. It was a little tight in the bicep but other than that it fit well in the chest and in the waist. It falls just below the belt. It was really nicely made and I ended up wearing it at the end of the night (due to not bringing my own jacket in December in the snow) and it kept me pretty warm and was really nice and cozy! So if you’re looking for a pea coat / trench coat that isn’t $500 then definitely buy this one!
