The rockers you picked out are non-guided. Others have machined the heads to either gain clearance or peace of mind. The issue is, some have gotten by with very close retainer to valve boss/guide clearance. thanksĭon't be this way or you won't get a tip. If so will these flat top pistons fit without any troubles?If they do indeed fit they would give 10.14:1 compression.Īgain PLEASE DO NOT POST IF YOU DONT HAVE AN ANSWER TO MY QUESTIONS. Will i need to up this compression to reach my 400+ horsepower goal? The stock engine with the 64cc heads has 9.4:1 compression. trying to stay around a $100 for these also. If someone could give me a reccomendation on which rocker arms to use that would be great. I would need to know what the specs of the camshaft i will need? I will not be doing any machining to the block so the camshaft must just slide in after the valve springs and rocker arms have been done. If possible i would like to use a summit racing or speedway camshaft under $150. I noticed that speedway and summit both have their own camshafts that are much cheaper than comp cams or the like. I would like to know if these rockers will work? I need recommendations on a cam and rocker arms that will work for this engine. I will be using the proper intake and a holley 750. I have read that i can use a high lift cam by using LS6 valve springs, and comp cams 787-16 retainers. I will be buying a 5.7L vortec engine complete and runnig with the 64cc heads. I have some questions please do not reply to this thread if you cannot answer what i am asking.
I know it possible to build a 5.7L vortec from a 96-2000 chevy truck to make 400+ hp with the change of a cam, rocker arms, valve springs, distributor, carb and a manifold with NO machine work required.
