City: Chatsworth, L.A. Area Engine: 468 Transmission: TH400 Year: 1969 Body_Style: Camaro
Engine is a 454 .060 over. Closed chamber (Iron) Rec port heads hogged out for max flow. 2.19, 1.88 valves. Eng is 11.7 comp. TRW pist, 3/8 rods, cast crank, 2 bolt main (yes all junk parts). Cam is solid roller 268/278 @.050 dur, 680 lift, on 115.5 lobe centers.
Edelbrock Super Victor intake & an 850 carb built by C&J Carbs (flow some 930 cfm). Engine idles at 900 rpm & runs on pump gas. Cranking compression is 175 lbs. 34 degrees total timing. Is in 3580 lbs. 1969 RS/SS Camaro (Similar to Bruce Kimmens car) Outlaw NMCA style car.
Street driven everywhere including at 75 MPH on freeway. Car runs 10.45 on motor w/4500 conv & brake (60ft is 1.5 sec). Runs 9.05 on 200 hp NOS plate (w/1.3 sec 60 ft.) And runs High 7's w/400hp plate, then switching to 400 hp fogger sys in 2nd gear (w/1.0 60ft. times). I've been racing this combination now for 2 years, same motor, & about 20,000 street miles accumulated. How's that for junk parts.
A blown race motor or large cubic inch race race motor is in the works. Let me tell you the secret to power with Big blocks is wide lobe centers!!!! Guess Why pro-stockers can idle at 1000-1200 rpm. The canted valve engines like wide lobe centers. Makes big power upstairs.

Eric has out together a really nice Big Block second Gen!
1980 Engine: 454 Transmission: Super T-10
car is sprts car style, lowered 2" front, 1.5" rear, Vette Brakes transverse leaf frnt susp, Konis, 4 whl discs, 6 point roll bar, sub connects, fast steer, etc. Engines are 454, both mk IV and GEN VI, 2.64 Super T-10, steel heads on both motors, 238/248 with .540, Strip Dom and Perfomer, a (real) 3310-1 780cfm now around 830, all the usuals. Car handles like a slot car even with B/B, no a/c, plastic hood. On a trip from L.A to Grand Canyon to Pheonix to L.A. got 17mpg avg. the entire way. Runs about 116-120mph in 1/4, depending on what mood it's in. So: B/Bs don't have to ruin handling. Don't believe all you hear. Just pay attention to the details, and weight-and-balance calculations. Just like building a hi perf airplane. That is the key to a canyon carving 2nd gen rat Camaro. Plant that sucker!
Mark P. from Bridgewater has a low-buck '68 with a 427 ci Big Block and has run a 12.01 et with it!
1968 Engine: 427 Transmission: Muncie M21

City: Harrisburg Combo: Big Block Engine: 454 .30 over Transmission: Tremec 5 speed Year: 1986 Body_Style: Z28
I had to have the 5 speed, it was worth the $2200.(fortesparts.com) Needless to say, that doubled the cost of the project ;-) 454 is from a suburban, 2 bolt mains, 9.0:1 compression, stock rods, stock crank(cast), stock intake manifold, and stock heads (3 angle valve job) topped with my poorly working stock Q-Jet (love it anyway) .540/.540 cam idles rough at 1000. *slightly* restrictive exhaust system includes BB manifolds emptying into a stock 3rd generation y-pipe, thats 2 inch pipes off each side into 2.5 inch single pipe back to muffler. Nice ceramic coated headers from Hooker will arrive today, then we'll see what happens ;-)
City: Philadelphia Combo: Big Block Engine: 402 Transmission: M-21 Year: 1970 Body_Style: Camaro L-78
Started with 2 bolt block out of 69 impala, steel crank, 7/16 dimple rods, forged 10.25 pistons. I am still using the factory 375 horse camshaft with 291 heads and 100 cc chambers, 1.72 roller rockers, and .051 head gasket. The cam is backed up 6 degrees to allow for more intake valve clearance. Intake manifold is a Weiand x-cellerator with one inch 4 hole spacer. Carb is a 855 cfm with vacuum secondaries. Ignition is mallory hy-fire 4 with rev control set at 6800 rpm. Hooker super comp headers with 2 inch tubes and 3.5 inch collectors and a complete 3 inch exhaust that exits the rear of the car. I use a center force clutch with a 4.56 rear gear and cal-trac bars keep it straight. Tires are BFG drag radials with 17 lbs. pressure at the line. So far the best ET is 12.74 at 110 mph and still getting faster. Sixty foot times are brutal with a 1.92 best. Shooting for Low 12's by end of summer. This car is raced in street trim only and is driven to all show events that I attend. It is also a lot of fun to drive around town, late at night of course!!
Future plans are to re-install original L-78 motor in the springtime.

City: Talbott Combo: Big Block Engine: 454 Transmission: TH350 Year: 1983 Body_Style: Olds Cutlass
A completely stock bottom end 1973 Suburban 454 with a true roller timing chain, stock 8.75:1 pistons, polished truck rods w/ARP bolts, a Comp Cams .550 292 hydraulic cam, bone stock heads with roller rockers and a Victor Jr. intake, 750 HP Holley, 4000 converter, 10 bolt with 3.42 gear 3 inch Flowmasters, ran 8.40 crossing the line at 5500 in second gear pulling power steering, alternator, and water pump. The car weighs 3600 lbs with me in it. Now I've upgraded to a 4.10 gear and with suspension tuning will hopefully run 8.00's and 8.20-8.30 on street tires. This is a car that I drive to high school on a weekly basis. Not bad for an 18 year old is it. If you have any questions email me I will soon upgrade to 12.5 to 1 compression and fully ported and polished heads which will hopefully propel me to around 7.60-7.70 in street trim. Then the aid of 150 horses of NOS should put me in the 7.10 range which would be rolling for a street car that I take dates out it.
