These cams make an improvement you can really feel. Higher lift helps mid-range power and extra duration helps the top end. These cams will pull right up to 7000 rpm with ease. We have 3 different grinds available. The 274 cam is excellent for mild builds while still retaining streetability. The dual pattern 280/274 is great for those who want something a bit more aggressive than the 274 and also very ideal for boost. If you’re building a stroker M20 engine with a bit of compression behind it we would recommend going with the 284 grind!
Due to the difficulty of keeping good core camshafts in stock, you MUST SUPPLY YOUR CORE IN ADVANCE. You will need to purchase this regrind service and ship in your own good core M20B25 camshaft to be reground. We do NOT stock cores any longer. Once we have received your core, please allow up to 1-2 weeks before return shipping.
