These kits are intended for experienced engine builders. Some clearancing, fitment, or other engine building "tricks" may be needed. Hemis may need pistons notched for valve clearance. Compression rations are estimates and may vary due to deck height and crankshaft tolerances.

307 Cam not recommended for Hemis.


Aluminum or Honda flywheel recommended. Stock flywheels are prone to failure and very DANGEROUS
