    331 Stroker... Input Please.

    Sounds good!! the TFS2 cam will work fine.. I would suggest the smaller Runner CC heads, install the TFS2 cam in at 2* advanced, and have a blast!! Try not to get into the HUGE runners and valve size for a dual purpose car... yes?? The Torque is the important factor for a street car.. the HP...

    347 stroker PISTON SWAP

    Yes the 347 needs a 347 piston do to the compression height of the 347 piston. Be carefull and check out the rods... there is a piston for the 5.4 rod ( most common) or a shorter rod. The easy way is to look at the piston.. if the oil ring goes around the wrist pin, then the 5.4 rod is the one...

    Boss Block to buy or not to buy?

    It is a great block.. however I feel it can be a huge overkill if you are not going to be at the 500-600 HP range. then you have 1500.00 MORE into your engine that COULD be spent else where, yes?? $1500.00 is a LOT of add'l mods.. like Suspension/ tires ect!! Pulling a lot of power out of...

    gt40 p heads with flat top pistons?

    The P's will allow a lot of power on the 347 with the TFS cam, however, they would be much better suited for the 5.0!! You can pick up a set of forged pistons for 450.00, and then add ARP rod bolts/ ring set/ bearings.. possibly a balance ( I would).. I agree that it would be a "better deal"...

    gt40 p heads with flat top pistons?

    I agree... you dont know enough!! mic it and see!! the question would be why use the flat top 86 piston ( No valve reliefs) on a re build?? HHHhhhmmmmmm.... But.. the cam will not kiss the pistons ( save the 86 no valve relief pistons) when you pull the heads for a change... see what is...
