How much HP in the LT5 cylinder head? - ZR-1 Net Registry Forums

you bet todd and thanks for posting all the info on your build

quite an accomplishment. I believe I can count on "one hand" the number of ZR-1s over 700 hp.

hearing heads that flow up around 370 is really good news. I was there with the shop while yours were being done. no doubt they came out well as you are putting out great power

a 427 LT5 is a magical set of numbers

I'd like to go bigger bore on my motor but I need to wear out the one I have (it will likely outlast me!!)

daily driving the car now, I figured hey, it's got 80k, and more miles equate to more grins so like frank said

"who are you saving it for" nobody but me. the car is so much fun that the turbo z06 is "on the top of the rack" and the ZR-1 is getting all the attention.

there really is something special about the beast.

keep more details coming about your car todd! like to hear your experiences tuning on the radical cam shafts.

any chance you are making it to carlilse this year?
