Default Re: Hi all! New Guy here, Low Buck Comp build, E/ED

I know its been a little while, but we are still plugging away for the 2014 season opener. This is where we are at, tight now. Car is ready, rebuilt 3rd member, stepped up the gear, new motor plate, switching from the sbc to sbf, (which is the same as my little inline Ford. Just finished boring the block tonight, I bored all cylinders +.150 to accept these steel Massey Ferguson sleeves I purchased off eBay for $8.00 each, sleeved all 6, so my final bore is going to be 4.00 and will be the stock 240-cid displacement. The main reason for this was the use of the 2-sets of std. bore 351-w domed pistons I bought for $150- TRW forged, old heavyweights.. I'm in the process of lightening them up on my old Bridgeport, then I will re-work the dome a little, and gas port. The cylinder head is a stock 240 at the moment. I bought 3-240 motors at a semi local junkyard for $100 a piece. Cleaned all the heads, and now ready to start porting. With the big 2.02 int-1.60 ex. chevy valves, and a little milling, I'm coming up with right at 12.1cr. not very high, but with the .225 small dome 351w piston flame travel should be fair. The stock 351W compression height is something like 1.765, and a connecting rod out of a Ford 5.4 Mod engine fits perfectly once cutting the crank rod journals -.020. For around $300 they make a H-beam rod to replace the stock 5.4 mod rod, but I purchased a brand new stock set with bearings for $125.. they were left over at a local Ford dealers parts counter for a 5.4 Triton truck motor rebuild that never happened. The valves in the picture are high$$ Manley Titanium pieces for an SB-2- guy bent one and only had 7- got those on Ebay for $50 cutdown the stems a little reface and they will be right on! Again, the old Clifford 2-4bbl intake, an $90 Ebay find, going to heilarc some 2" spacers and rework for 2-660 center squirters I have had for about 20 years on the shelf. The cam is a special Mech-flat-tappet that my cam grinder donated for promising to run a couple of his decals. Stock 289/302 solid lifters. Shortly glide case I just cut the bell off. Going to use a J&W bolt on Ultrabell. I still have a few parts and pieces I'm scrounging. Bought a set of 14 BBC 1.7 SS-Comp Cams roller rockers for $75 in the picture of Racingjunk, I will be using those to start out. I'm sure alot of people would disagree how I'm doing this. But being on a dead nothing budget in the high dollar world of Comp, whats to lose?? The engine? I may have $2500 in the whole engine when done. Just making sure I have a good sportsman diaper! lol. I know better to think this will be a record breaker, but that is not the goal for the first engine. I feel, at the 240"cid-6.00 lbs per cube, we have to weight around 1450lbs. Hell, if this time bomb can make close to 400hp we should be able to crack the index, or be close at least. If so I'll have ambition to build a better piece. Trying to go at this like they did in Comp back in the 1970's using what you can get at junkyards and for low cost. I've been told I'm wasting my time, and should call Gurus like Ambrose-Arnold-Treadwell, that have already done this successfully. and don't get me wrong, I have the utmost respect for those guys. I'm sure I'll end up contacting them for advice at some point. But for now, I just want to see what this hodgepodge mixed concoction of junk coming out of my backyard garage will do without spending much money.
