Solid Roller 268/275 LSA 106 Camshaft Ford 302W 351W Windsor

COMP Cams 35-780-9 Solid Roller Camshaft – Ford 351 Windsor (298DR-6)

A mechanical (solid) roller camshaft from COMP Cams for the 351 Windsor and Windsor-based strokers run hard at the strip. The 298DR-6 grind lifts .696" intake / .672" exhaust on the factory 1.6:1 rocker ratio, with 268°/275° duration at .050" and a tight 106° lobe separation. It comes on from 4,200 rpm and pulls to 7,200, so it's matched to a high-compression, high-stall combination — think 12:1 or more with a 4,500+ stall converter.

Fits: Ford 351W (351 Windsor), 8-cylinder, 1969–1996, in 351 to 377 cubic inch builds.

This is a competition grind. With that duration, lift and rpm band it wants race fuel or a dedicated tune, a loose converter or a manual, gearing to suit, and a valvetrain built to match — it is not a street cam and it is not a bolt-in upgrade for a stock 351W. Building a streetable Windsor combo? Call us first; there are better-suited grinds. 

Sold individually (camshaft only). Lifters and valve springs are not included — see "What you need to run it" below.

Comp Cams 35-780-9 Specifications

Recommended Upgrades & Valve Springs: 

This cam is part of a package, not a standalone swap. To run the 35-780-9 you'll need:

• Valve springs: a solid-roller dual spring rated past .696" lift with the open pressure to control the valve at 7,200 rpm. Our DRP-9550P-BBKIT Proline RPM solid roller dual valve spring kit is rated to .770" max lift (250 lbs seat @ 1.900", 550 lbs/in) and ships complete with 7° retainers and locks for 11/32" stems, bronze-guide locators and Viton seals. Confirm the installed height suits your heads before ordering — our team can check this with you.
• Retro-fit solid roller lifters (link-bar style) — not included with the cam.
• Distributor gear compatible with a billet steel cam (bronze or steel composite). A stock iron gear will not survive on this camshaft.
• Pushrods checked for correct length once the valvetrain is assembled.

Worth checking on your combo: piston-to-valve clearance at this lift and duration, converter stall, compression ratio and fuel.

Our sales team of actual engine builders are on hand to help you spec the lifters, springs and gear to suit this cam so it's right the first time. Call us on 1800 351 351.
