The Texas Speed 427 SBC Long Block with Solid Roller Cam is a complete 427 cubic inch Small Block Chevy long block assembled by Texas Speed on a Dart engine block with AFR 1132-TI aluminum cylinder heads, a 264/270 solid roller camshaft, T&D shaft rocker system, valve covers and an intake manifold. On the Texas Speed dyno the engine produced 615 peak horsepower and 570 lb-ft of peak torque, and Texas Speed publishes the dyno sheet for the full power curve and test specifications.
The long block ships with the engine cradle, crate and 16 quarts of break-in oil, and the buyer chooses whether to add a carbureted or EFI completion kit. Completion kits ship separately and are installed by the customer, since ignition, fuel system and induction parts are not pre-installed on the engine. Distributor timing, fuel system setup and final tuning may be required, along with vehicle-specific fuel, cooling, exhaust and accessory components. Texas Speed notes that solid roller camshafts require periodic valvetrain inspection and lash adjustment as routine maintenance.

FAQ
What is included in the Texas Speed 427 SBC 615 HP long block?
A complete 427 cubic inch Small Block Chevy long block on a Dart block with AFR 1132-TI aluminum heads, a 264/270 solid roller camshaft, t&d shaft rocker system, valve covers and an intake manifold, plus the engine cradle, crate and 16 quarts of break-in oil.
How much power does the Texas Speed 427 SBC long block make?
Texas Speed dyno tested this engine at 615 peak horsepower and 570 lb-ft of peak torque. Results vary with fuel quality, exhaust, tuning and supporting components, and the dyno sheet shows the full curve.
What is the difference between the carb and EFI completion kits?
The carbureted completion kit finishes the 427 with a carbureted induction package, while the EFI completion kit supplies an electronic fuel injection package. Either kit ships separately and is installed by the customer, or the long block can be ordered alone.
Is the engine ready to run out of the crate?
No. The long block includes valve covers and intake manifold, but ignition, fuel system and induction parts are not installed. Distributor timing, fuel setup and final tuning are required, along with vehicle-specific fuel, cooling, exhaust and accessory parts.
What cars does a 427 SBC long block fit?
It is a Small Block Chevy engine, so it fits classic Chevrolet cars and trucks and any chassis set up for a Small Block Chevy, such as the 1967 to 1981 Camaro, 1964 to 1977 Chevelle, 1962 to 1979 Nova and 1961 to 1987 C10. Motor mounts, headers, transmission and accessories must match the vehicle.
Does a solid roller cam need extra maintenance?
Yes. Texas Speed notes that solid roller camshaft applications require periodic valvetrain inspection and lash adjustment as part of routine maintenance, which is the trade-off for the higher output of this version.
