you must not read to well. it says LS7 block. not LS2 resleeved 427. huge difference bud. this is a LS7 wet sump conversion.

 

I was just about to say the same thing:

for those too lazy to click on the link

ur TSP 427 cid LS7 short-blocks offer the best durability for the best price possible! GM's new aluminum LS7 block debuted in the 2006 Corvette ZO6. It comes from the factory with a 4.125" bore, and it will accept the same timing cover, rear cover, valley cover, timing set, and lifter trays as the LS2! Our standard short-blocks come fully-assembled using an Eagle 4.00" stroke crankshaft, Scat H-beam 6.125" connecting rods with upgraded ARP 2000 rod bolts, and Diamond Racing 4.125" flat-top pistons with -3.8cc valve reliefs. The price listed also includes the appropriate timing cover with camshaft position sensor, valley cover, rear cover, lifter trays, standard LS2 timing set, and the necessary cam sensor and knock sensor harness extensions to retrofit it into an LS1 vehicle! We offer many upgrades for our short-blocks, and we will custom-build one for your application! We try to keep a few 427 cid LS7 short-blocks in stock, and if you order one of our in-stock short-blocks it can ship as soon as the next business day! Our LS7 short-blocks also include the engine crate, engine cradle, and truck freight shipping charges within the continental United States! We can also assemble your short-block with your choice of camshaft, new camshaft retainer plate, and ARP retainer plate and timing set bolts for an additional $399! Feel free to give us a call, and we will help you select the parts that will best suit your application. You can also call us to check if any of our engines in stock will work for what you are looking to do! All short-blocks will be built using the 2005 and older 24x tooth reluctor wheel on the crankshaft. If you have a 2006+ vehicle that you will be installing our engine in you will need the updated 58x tooth reluctor wheel! BE SURE TO SPECIFY IF YOU NEED THE NEW RELUCTOR WHEEL WHEN ORDERING!

 

Hey Zach, that is a great price and Trevor is working up a full est at this time. Will this accept a wet sump oiling system? Thanks for the help.

 

Forgive my ignorance but is the LS7 block better and/or stronger than the resleeved LS2 block? Also, in your oppinion for a 550ish rwhp N/A application would you go with the upgraded crank and Oliver rods? Or would you consider that overkill for that sort of power? Thanks

 

i think the rod upgrade would be over kill... the callies crank upgrade maybe nice to have due to their reputation for quality...

LS7 vs resleeved LS2 is debateable maybe if you exceed 1000rwhp the resleeved maybe stronger. there are actually a couple of very debatable threads going on.

 

I wish my 346 could have lasted a tad bit longer. I shure would have gotten a 427 instead of a 402. I love my 402 though, great job at TSP. Do you guys take trades, LOL j.k

 

there always something else coming out that is better. there is no telling what we will see by this time next year. performance parts are moving about as fast as microchip technology moves, every 9-18 months there is a whole new level introduced. but im right there with you. if this LS7 427 was out in March of this year, i would have spent an extra 2k and went with this short block.

 

Guys this pricing is using a prefect GM LS7 block!! This is a intro price for a very short time! We only have a couple of them going together at this price, so you guys better act fast!!

 

If using just a normal LS1 pan it can be set up as a wet sump

 

427 c.i Long block pricing will be up on the website sometime today as well!!

 

oops, my bad

 

zach the long block is not up yet let me know im intrested in getting one.....

 

YEAH, waiting to get the pricing on the longblocks!!

 

Shipped my heads off to them today for flow bench test to make sure they will work with the big cube motor if all is ok with my current heads will be ordering one. If heads are not ok will need to look at new heads as well (I hope not) We are shooting for 550 rwhp!!! Will keep you posted.

 

wonder if the price is going to drop ~700 since the LS7 bare block has gone down that much

 

From what I have been told it will be going up. They actually discounted the total cost of the shortblock over 2k to get that price. I have been looking at a 427 for months and have several estimates and I am jumping all over this because it is the best affordable package out there. Granted other companies may use a little more expensive parts (doesn't make it better imo) They have everyone beat on this deal.

 

Do TSP motors come balanced and blue printed?

 

 

Yes, they also degree the cam and check p to v as well. I have been beating this guy up for over a week with questions and e-mails and he took the time to help me out and I feel very comfortable with TSP building this motor. I have never dealt with TSP before this, I have always heard great things about them and once I saw the price I had to check it out.
