HPR 468 LS7, WCCH Brodix BR7 heads, and G1Pro custom billet intake build
Well I decided my H/C/I LS7 625rwhp wasn’t enough N/A power for a daily driver. Lol!! So now I have Erik at HPR building me a 468 LS7 N/A monster. Here are the specs I have so far. GM LS7 block with Darton sleeves K1 4.250 stroke crank cut down to except small journal bearing rods Callies small journal bearing rods HPR custom 4.185 dome pistons by CP HPR custom hydraulic cam 26*/27*....74*/74*...112 lsa Brodix BR7 BS heads done by WCCH with Ti intake valves and inconel exhaust valves G1Pro custom billet with long runners (7inch runners with 10% taper full radius bell mouth) PAC springs Crower 1.8 shaft mount rockers with needle bearing tip Katech “red” ported oil pump C5R timing chain. compression will be around 13.0 since I will be running E85. ARH 2inch headers with off road 3inch xpipe. Can’t decide wether to keep my Corsa exhaust or dump it Goal is 700+rwhp https://cimg2.ibsrv.net/gimg/www.cor...0b4d30d0f6.png https://cimg3.ibsrv.net/gimg/www.cor...dc8d038a4.jpeg https://cimg4.ibsrv.net/gimg/www.cor...2845243a7.jpeg https://cimg6.ibsrv.net/gimg/www.cor...b050874f1a.png https://cimg7.ibsrv.net/gimg/www.cor...3f6af003fd.png https://cimg9.ibsrv.net/gimg/www.cor...92cc4c6edb.png https://cimg1.ibsrv.net/gimg/www.cor...295844cc99.png https://cimg2.ibsrv.net/gimg/www.cor...7d56026b27.png |
Killer sounding combo! One question.... will that G1pro manifold deliver enough air at high rpm?
Assuming you will be spinning it to at least 7k... |
Looks great man. Looking forward to the final numbers.
|
This will be fun! |
Ironically, that's almost my build as well LOL
I'll be running a different intake, though. |

Nice! Just as a note, the Hinson c7r chain is 150 on amazon. I think hinsons web site even recommends the c7r chain these days. Just a though, it’s pennys in difference on the cost. |
When will it be done?
|
Badass!! |

Awesome build. Sub'd.
For the timing chain, I'd stick with the Katech C5R chain. There is no evidence that the Hinson "C7R" chain is superior in any way. Further, Katech never once broke a C5R chain when they built motors for the factory Corvette racing team, and that included the 24 hours at LeMans endurance races. It's a race derived, race tested and proven chain. |

I haven’t seen any, but if there are it would be nice to know before I go in on the C7R chain as well lol. There should have been a C6R chain to rule them all... |

Not questioning you, as the Katech C5R chain has been proven. But have there been any reports of the Hinson C7R chain broken?

However, the Katech C5R chain is also the same chain as was on the C6R and currently on the C7R. It's just called a C5R chain. It's made to Katech's specifications and has never failed in endurance race conditions from C5R to C7R. Same chain all along and same chain you can buy. |
