351 build
I am in the process of building a 351windsor on the cheap to thrash at the local strip. I have been working with a local speed shop and just got my heads ported and set up for up to .600 lift. I am thinking about using a comp cams hydraulic flat tappet cam instead of the retro fit roller that the shop is suggesting. They are good folks, but they don't have the budget restrictions that I do. My question is this-on a strictly horsepower sense, just how much power am I going to lose by going this route ? The cams spec out very close to the same in terms of duration and lift as well. I understand the difference in the two in theory and know there will be some loss going with the older style hydraulic cam. Also-the springs I have installed are 27 lbs. heavier open than what is suggested for a hyd. cam-will this pose a problem or am I stuck with going high dollar roller now?? Any help very much appreciated!
