Need your opinions/thoughts for engine upgrade

[Jay Hilliard]

I have a 355 6.250 rod SBC with 10.8 CR.
Comp cams hydraulic roller 230/236 @.050 - .510/.520 lift
Bowtie heads 184 intake runners with 2.02I -1.60E. Exhaust ports had some minor porting. Currently has beehive springs with 1.7 Int -1.6 Ex crower rockers, stud girdle and rev kit. Cam lift with rockers us now .570 ish lift on intake and .555 on exhaust.

I am now wanting to change my cam to a solid roller, because I am not happy with the rpm's of a hydraulic roller. 6700rpm's is the limit when peak HP is at 6300. I want to be able to turn this motor 7500 if I need to and I know a comparable solid roller will allow me to turn the engine the rpms I am desiring.

Along with this cam change I was thinking about switching to some aluminum heads. I was looking at the Brodix race-rite 200 heads. Will or shouldn't these heads help with my configuration of new cam etc?

I know this is a long post, but wanted to give all info, so hopefully you guys can give me a somewhat informed opinion.

thanks.

My opinion: When you go solid roller you should really take advantage of the profiles only a solid will give you (very steep ramps, etc.) And if you do that, you really should do it WITH new heads, as you mentioned.

Don't bother unless you can also do the heads at the same time. I'm a fan of AFR, but Brodix are nice. However, if you want to chose one or ther other- do heads first. :yes:
