Looks good if it's a good build (any guarantee?) I just paid almost $1400 for a stock L98 rebuilt engine, so if you can get that much HP for for that price it's a heck of a deal.

Yes it does have a guarentee. It has around 325 Horse and 340 Toruqe. Would this be an easy swap for me from my 305 TBI?

Looks nice. However the intake does look pretty high. If you have a stock hood you might want to check that out.

I like it though.

The engine looks nice, though my only concern would be using the stock tbi on it. Some say you can get about 300hp outta the stock unit, though I think a 2" tbi would be a safer bet. In that case you would need to have the intake bored to 2", or go with a different intake

I just put in an L98 engine and put my TBI from my L03 on it. Runs great. (just gotta get some headers to unleash it). I went with 350 cop car injectors and a cop car chip from TBIchips. If you do a little research on the engine swap board and this one you can find all kinds of info on doing the swap.

Well, as far as air and fuel go, you will more than likely need a few things to make 310-325hp a reality. !st, you will need a better than stock fuel pump. I recommend a Walbro 190 or 255.
Second, you will want either a holley 670 or 454 tbi with 2" bores. Though it has been estimated the stock tbi can support close to 300hp, the bigger tbi will be a sure bet. Third, you will want larger injectors. The holley 670 comes with 65pph which should be good, or if you went the 454tbi route and kept the stock pod, then you would still want larger injectors.

Ouch 350$ for shipping. What BS. I had a engine delievered from paceparts and it was 130$. They say they will pay 250 or thr 350$ for shipping. Because they are making extra bank on the shipping prices. I hate that.
