Just wanted too get some opinions on victory race engines short blocks? Any issues with quality,turn around time? I'm thinking of buying there 396 race short block for 3700.00. I spent all of that on my 355 and i don't want the issues of having a local shop building me a grenade so to speak. Has comp-star crank,rods and S.r.p pistons i believe. I plan on using my plate kit and le3 heads along with one of Lloyd's custom ground cams . Any opinion is appreciated

 

I can't comment on the engines, but maybe they can upgrade the pistons for you if you're going to spray it.

 

They're forged pistons too begin with I believe. I've found mostly great reviews about them. A few bad ones but honestly that happens too every business at one point or another.

 

SRP is a forged high silicon piston -there are tougher pistons for a nitrous application. Do some research on it and you might see what I'm trying to tell you.

 

I'm sure i could substitute for diamond pistons or j.e . I sprayed my speed pro pistons all last season and did absolutely no damage too them. They are still in mint condition. Surprising enough the only issues with my motor now is a bad lifter. I want the extra insurance this year though as I started late last season. I ran the 10.8 on shaved stock heads. Fresh rebuilt 355 xfi280 cam and a 150 shot. This year though I'm going with a performabuilt 700 Dana 60 and a 396 stroker mated with my le3 heads and a custom ground can from Lloyd. I'm expecting low 11's on motor. I'm gonna have the car dyno tuned at Kennedy's in buffalo. Won't stock pistons hold upto nitrous as long as your timing is correct and your afr is perfect to slightly fat? I do run a eugowb02

 

while that being 100% true. the levels of nitrous 95% of people use is well within the design limits of this piston. i would not think twice about feeding it anything around a 250 shot. the rod length and compression height is more important at that point. chances are with a 6" rod and a 1.062 CH on big shots make sure your tune isnt out or you could burn it into the ring land easily enough. id build a 383 IMO if you are planning on regular spray. too much rod/stroke for the deck height.

 

So is there a noticeable difference between a 383 and 396 then? I don't wanna build anything either that's why I'm interested in victory race engines short block. My heads are le3 and I believe they are 58cc chambers. I'm looking for 11.5-12to 1 s.c.r. the car will have a full cage as well. Might see light street work but mainly a weekend warrior strip car. I only run 98 unleaded in the car and its a bit pricey for a daily driver. The most ill ever spray is a 200 shot. I ruined my stock transmission this past year because of the added torque from the 150 shot. Surprisingly the 10 bolt held up extremely well. My mechanic installed an ultimate cover in it and said it looked perfect. I still plan on a Dana 60 though because I never once sprayed the car off the line in fear of shearing an axle. The car made 502 ft lbs on a mustang dyno but only 390rwhp. Surprised it got me into the tens without spraying 1st gear but as always I want more lol

 

a 383 is a 4.030" bore x 3.75" stroke. a 396 is a 4.030" bore x 3.875" stroke. all the displacement is gained by the stroke. personally i don't like that much stroke in a 9" deck motor. too many compromises for too little gains. compression will be met on either build. the 396 will net higher compression for a given chamber due to the increased stroke/displacement. from a nitrous standpoint though the 383 will have a better piston design and will give you more of a tuning window and resistance to a nitrous related piston failure IMO.

 

What are you talking about design limits for? - You apparently have a mechanic who builds your engine(s) for you and you have a tuner who tunes your engine for you, which means you don't do any of that stuff yourself. How are you going to make sure your tune is on if you don't even know how to do that yourself? Saving a couple hundred bucks using cheap pistons on an otherwise decent build, when you know you're going to spray it, is kind of silly.

 

Don't know if they are still a sponsor here on Cz28.com but I've heard good things from VRE.

 

U mixed up posts Kevin fyi. No I don't build motors or tune them. All I stated was my speed pro pistons held up too over 100 runs with a 150 shot. I did change part of my tune because the Solomon tune had way too much timing. I went through and edited my timing table in tuner pro. I monitored air fuel ratio with a a.e.m wb02. The motor never detonated or pinged. Checked all plugs periodically too ensure there was no detonation. Obviously speed pros are cheap but it was what I could afford at the time. I don't want a local mechanic building my motor,hence the post on v.r.e short blocks. I want a motor that's ready to rock not someones cob job around here. They do offer diamond pistons with other short block combos so maybe ill inquire about them. Would probe pistons be a better option than the s.r.P's? I know alot of guys running them in high horsepower apps.

 

Don't know if I mentioned it or not but the car will be going too Kennedy's to be dyno tuned no mail order for me ever again.

 

nothing wrong with srp at that power level. a buddy and I run a 331 ford in a stock suspension 10.5 tire mustang. dart block, 331 cid, box stock AFR 185's!, twin 61.5mm garrett turbos. scat external balance crank!, scat h beams w/arp2000 bolts and srp dish pistons!. car makes about ~1200hp at 25psi. motor has lived 5 years of abuse! car runs 8.20's at 170mph. nothing wrong with srp pistons, but they are at their limit in that case. if your tune is good it will live, its when you put the burndown tunes and/or miss the mark is where you find weak links fast. a more robust piston would give you more insurance in that case.

i also ran srp's in my old 355 sbc and made 700fwhp dynoed with a 150 shot, with srp pistons. ran 10.0's my bbc has 25 y/o TRW boat anchor slugs in it, and it sees 150-200 shot and made 900fwhp dynoed, runs mid 9's on a 150 shot. my 383 n/a LT1 has the best pistons and the least power of the 3, mahle coated pistons in it fwiw .

 

Call JE and ask them which piston is right for your application...

 

Appreciate it guys, thanks for the help.
