Well, i am wanting to up the power of my 406. I don't want to have to change (again)out the rotating assembly at all. I will however change out the cam. I have been contimplating the idea of a Solid Roller cam. I have a Hydraulic Roller now in it. It is a Trick Flow (TFS-31402002) .246/.254 duration at .050 and .558/.558 lift with 1.5 rockers. ad a 112 deg seperation. I was thinking of going bigger up to somewhere close to .600 on the solid cam. I know that the solid would make better numbers for the motor and it is mostly for the track anyways. I also wondered if i was to keep the current cam and just change out the rocker arms to a 1.6 ratio and just kind of trick the cam into thinking it is bigger than what it is really.
I have a set of the Trick Flow heads that are 64cc chambers and 195cc intake runners with 1.46 valve springs. I have a Victor Jr and a 750 Speed Demon on it. It is running 10.5 compression and makes good numbers. It has chasiss dynoed at 439 hp and 437 trq. I know is pretty good but i want to squeeze the most out of it with what i have now and get better low end number in the sixty and drop my times in the 1/4. I run a best of 11.96 at 115 and a 1.75 sixty with a 3.73 gear and a 3400 converter. I have a NOS Cheater System for it but want to wait to use it till i have exhausted all other means by motor with what i have. I know this is a alot of questions but sitting over here in Afghansitan makes a fella think alot of the possibilities. Do you think some port matching and polishing would help some too. I am open to any and all advice and willing to do what it takes to get it right.
