I have the TSP 427 and have nothing bad to say about it. I do not think you can go wrong with any of the site sponsors though.

^^^^^Definitely the best price:value.

No brainer....it's the guys that won Lemans.

Example -Read about their LS2 block prep that they use in the value short block.

Look at the eng. prep pics Jason has posted. Friggen "Clean Room".

They wouldn't lend their name to anything less - than best value.

(I sound like a cheap disjointed commercial )


fwiw.

value has very little to do with your product and more with what he is looking for, you cant attest to value without knowing what he needs the motor to be capable of, and since he didn't post that info, I gave him another option.

SLED,

Very, very nice prices BRO and some of the best I have seen! What is the turn around time on your forged 346/7 LS6 blocks in case my stock LS6 takes a dump this season with my D1SC blower in my 02 Z06?!

Thanks Underboss, you can add one option for $200 and get a hellfire ring set, great for nitrous or turbo.
I usually have 347 and 402 kits in stock balanced, just have to machine the block to the pistons being used and about 2 weeks its shipped.

Sounds great, will file this away for a rainey day and I have heard great things about your engines and your LS1 tuning prowess, from the wild Canadian drag racing Bunch on the corvette forum, where i am commonly known as BLOWN ECS Z06!

I am still rounding up one maybe 2 guys needed to complete the best LS1 shop in Canada. Give me a few months Thanks again buddy, I'll see you over the CF later!

Go with the bigger bore 427 LS2 shortblock. One of the best values around. The 4.125" bore will really help those big valve L92 heads. 600 shouldn't be a problem if you don't mind some lump.
i have a 427 and 454 rotating here. I can get a block in a week. I can get you one in a month. Check out my website
Thanks
Dave
