Currently had my engine dyno'd. Am using a hydrolic roller cam ,and stock ported lt1 heads. Granted that this was on an engine dyno but motor put out 557 FWHP and 490 PDS torque N/A. Looks like it will be a couple more weeks before I can test this combo at the strip. Persision Industries now makes a lock up torque converter for the TH400, am waiting for them to make my valve body for tranny and to ship my Torque converter.

 

I cannot be 100% sure but didn't mindgame have over 500rwhp? He was on a stock short block with chev 15° heads converted to reverse cooling. Then P&P with a custom hydralic that he said idled like a well tuned CC306? His track time was something like high 10's but he was kicked off because he didn't have a roll cage. Doesn't anyone else remember that thread? Or am I just dreaming up random **** lol

 

I'll let you know when i get the shop in gear.

 

Keep dreamin...j/k... Mindgame had a 383 with custom pistons, coated this and that, modified intake for 18* heads, custom headers, etc. Totally killer, but a bit pricey for most people.

 

Yea maybe that was it. Except I remember it being a stock bottom end still. But really, thats a mean N/A 383 setup. I don't think many LT1s break 500rwhp even with 383cubes.

 

IM over 400hp at the engine and I have a 224/230 112lsa and homeported heads and stock bottom end so I guess that aint too bad. Havent gotten it tuned yet either and I could trap 114s all day long on a stock clutch that isnt doing so well. we'll see when I do the clutch on monday. Ad get a dyno tune later this month. I guess 500 FWHP is possible with monster cam and awesome heads, but it would be pretty hard and probably not too streetable

 

Awesome, what did the heads flow? Peak RPM?

 

Peak rpm was 6900. Was still pulling 529 fwhp at 7400 rpm. Torque peak was at 5200 rpm (493pds) Had 432 pds torque at 3900 rpm. Am at work right now and don't have the head flow sheet with me..

 

Aftermarket ECM? LT1 castings?

Impressive numbers .

Heads are LT1 castings.
Am using ACCEL DFI ecm.

 

I would just like to mention those are STOCK lt1 castings, not AFR castings or something like that. Jeff how much longer before track debut? Im gonna come watch take some pics etc.

 

Looks like it will be atleast another 3 weeks. Hopefully we will here something from Presison Industries the first of next week. Just want to be able to get some runs in before the year is up. Will let you know when we are going.

 

Good luck keeping that block together with the N2O. No matter if you fill the block your still not going to have the strength where you need it.

 

youre right it mite not but its prepped with all the tricks i know.partly filled block resleeved like a bow tie blk.i am trying this on lt1 type heads going with afr race hds & a hdyr roller.will it make dont tryin my a$$ off.i 396 small blk for (tradtional setup small blk)for a friend nova made 698hp fuel injected 23 dgr hds.so i think its possible if not i gave it all.hopin for it done buy 1st of year on street by spring.

 

any updates?
