500 hp sbc kits

[grumpyvette]

this is interesting and probably a good deal compared to most kits I see, listed as a 500hp kit
http://store.summitracing.com/default.as...p;x=35&y=12
TFS-K314-500-450 is the part number. Summit has it for $1750
I find this kits info mis-leading in that they don,t go into the short block requirements NECESSARY to make the combo work
(youll need something like a 350-406 10.5:1 cpr shortblock)
Im running a set of TRICKFLOW heads on my 11:1 cpr 383 and Im making just under 500hp (N/A)( before the nitrous) but thats because I sellected to build an engine with a cam designed to maximize the potential of the 200hp nitrous system Im running, not the (N/A) results, theres nothing wrong with those TRICKFLOW HEADS that a mild port and bowl cleanup won,t fix, infact after that minimal work the heads slighly outflowed the 195cc AFR heads out of the box flow figures
Ive built several 383-406 sbc engines using
CROWERS #00471 hydrolic roller cam
http://www.crower.com/misc/cam_spec...=00471&x=28&y=4
and CRANES
# 118551 solid roller cams
http://www.cranecams.com/?show=brow...rtType=camshaft
with 10.5-11:1 cpr that exceeded 500 N/A hp
they require a 3.73-4.56 rear gear and a 3000rpm stall converter, plus other mods to work correctly
theres many other combos that will get you a 500hp sbc, and you don,t necessarily need a roller cam or those cylinder heads either, BRODIX,AFR,DART PRO 1 and several hundred cams can get you there

Here's the big debate, whether the 195cc heads will flow enough for 500HP. I think 210s would be better. Of course this depends upon the rest of the engine being maximized for higher flow. The 195s would improve the torque & lower the HP rpm.
