Info
Run up front with the 400-horsepower CT400 crate engine (often referred to as the “604 crate”) featuring Fast Burn heads from GM Performance Parts. Now, Learn About Speedway is offering this 604 crate engine as a dressed & dyno-verified package that is ready to race!
These IMCA-sealed 604 crate racing engines are based on the popular Fast Burn 385 street crate engine, but include a racing-only 8-quart circle track oil pan with dual kick-out design, along with a valve cover breather kit and special “kool nut” rocker arm design. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers.
The 604 crate engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons. The 23-degree, Fast Burn aluminum heads enable tremendous power in the small-block V-8 because of a unique chamber design that quickly and completely burns all of the air/fuel mixture – giving you maximum power. With the CT400 racing engine under the hood of your Modified or Late Model, you’ll put a “fast burn” on the competition.

Recommend seller. Items as described. Quality item, and the item was a good value for the price. Item was delivered in excellent condition.
Shipping time was excessive. This would be eBay’s fault, not the seller. Item shipped out June 16 from USA, and delivered July 8 in Canada. eBay definitely needs to overhaul their international shipping to provide better service for the amount they charge.

Fast shipping on the sellers part, the shipping company beat the heck out of the shipping box, (not sellers fault), item was exactly as described, great communication. Highly recommended seller.

I Love speedway , though this time they upset me a little .. waiting for wheels finally called and they tell me on backorder and 6 months before they will be shipped , they should have contacted me , or better yet , don’t advertise things you don’t have , but this is the first problem in well over 20 years . they are still on my top for sellers.

Great system for the price. Quick on shipping. Was shipped in 2 boxes….one arrived a couple of days earlier than expected and the other arrived a couple of days later than expected. It was all good though. Seller responded promptly to my question. Will purchase again!

Item as described, great product for the money. But Speedway needs to change their shipper – I was not home when this package arrived, and the carrier just threw the box on my front porch in the pouring rain – box was soaked. Couldnt they put it in a plastic bag?

Arrived in well packaged box. Quality of item is great with all (grade 5) bolts included. Condition couldn’t be better. Although arriving late due to USPS keeping the package in Bakersfield, CA for more then 4 days (maybe DOGE/Elon can fix next) the communication and tracking was a plus. A great value for anyone wanting to convert their YBlock generator to alternator.

Item came packaged well, fast shipping, good looking item, expect it will be working and functioning for years to come. Very happy with this vendor, communication was excellent while I peppered them with questions before purchase. Thank you.
